Description

The MFP Series™ of DC/DC converters do not require any external components to achieve all specified performance levels. They are a high-reliability, high-efficiency point of load converter for use with a 3.3 VDC input bus or a 5 VDC input bus. The MFP0507S model has the flexibility to be set for any output voltage from 0.64 VDC to 3.5 VDC. The converter operates from an input of 3.0 to 6.0 V IN with an undervoltage shutdown at 2.75 V, an overvoltage shutdown of 8.5 V and up to a 15 V transient for up to 1 second. The non-isolated, feature-rich MFP uses a Buck converter design with synchronous rectification. The design allows the unit to operate synchronously to no output load, ensuring high efficiency at the lightest loads without switching off the synchronous devices. Important features include a solid state switch, inrush current limiting, synchronization with an external system clock and the ability to current share allowing multiple devices to supply a common load. The MFP includes an internal house keeping supply that is active at inputs as low as 2 VDC and provides a boosted and regulated voltage supply for internal use. This internal supply is one of the reasons that this product can provide full power at very high efficiency at input voltages as low as 3 VDC. No external power source or external bias is required. The MFP converters are designed for the large, fast transient load currents typical to digital loads. See Figure 4 for a typical connection diagram. The MFP Series is intended to be powered by a fully regulated power source. Us patents Interpoint converters may use one or more of the following US patents 5,521,807, 5,694,303 and 5,631,822.

th e rMa l Co n s i d e r a t i o n s The MFP is designed to be mounted close to the point- of-use which, in many cases, may be on a printed circuit board. The high efficiency of the MFP reduces the issues normally associated with the converter’s internal dissipation. The maximum internal dissipation occurs when the product is configured as a 3.3 volt output at full load. This condition will result in a dissipation of not more than 1.83 watts. This dissipation is nearly uniformly distributed over the base area of 1.4 square inches. Full load power loss is largely independent of output voltage, for instance at 0.8 volts and full load the internal power loss maximum is again 1.83 watts. In order to determine the cooling or heat sinking requirements in the application, the maximum product power dissipation should be calculated from the product efficiency and output power. Graphs and tabled values in the specification table can be used to find the efficiency given the input voltage, selected output voltage and output load. The internal dissipation, difference between output and input power, can be calculated from the equation below. where: poUt = output power ɛ = efficiency Many applications will not require special efforts at cooling, however, this depends on ambient temperatures, adjacent components, and other factors. If product cooling is required for safe operation convention and/ or conduction can be used. Thermal considerations require that the base of the MFP be maintained at a safe temperature of less than the maximum rating. All components internal to the MFP are bonded to the metal base of the package. The base is the surface that is important if conduction cooling is used. It is a good practice to bond the device to the PCB or mounting surface with a thermally conductive pad. Such pads provide some degree of conduction cooling to the mounting surface depending on the amount of voiding at the interface. In the case of the side leaded MFP package, this thermal pad will firmly locate the device to the surface so that the lead connections only manage the electrical requirements and not the mechanical requirements. In Figure 3 below, the thermal rise internal to the MFP can be seen to be only 6°C. This low thermal rise gives the end user more flexibility in board design options to meet applicable derating guidelines. tHermal anD moUnting consiDerations pDiss = poUt (1 - ε) / ε F = thermal resistance of converter attachment to board ∆ T = PDiss x F tcase = tbase - ∆ T Crane Aerospace & Electronics Power Solutions maximum Flexible power (mFp) single output point of load tecHnical preview: mFp0507s, 3 to 6 vDc in, 7 amp, Dc/Dc converter Page 9 of 19www.craneae.com/interpoint Technical Preview: Contains preliminary information MFP0507S Technical Preview Rev D - 2010.11.18 Fi g u r e 3: inFr a r e d iMa g e, MFP a t Fu l l lo a d w i t h 6 Vin, 3.3 Vout

Mo u n t i n g Co n s i d e r a t i o n s Interpoint recommends Chomeric’s double-sided adhesive materials for attachment of the MFP to a circuit board or metal surface. Because of the MFP’s efficiency the thermal characteristics of the Chomeric materials are not required even though the Chomeric material provides good thermal conductivity. The following information refers to products attached using Chomeric double-sided adhesive. Vibration Testing The MFP was tested in Random vibration using both the T1680 and T404 to mount the units to an aluminum vibration fixture. Testing was performed to the most severe level in MIL-STD-883 Method 2026; Condition 2, Letter K, overall G RMS 51.1, for 15 minutes per axis, 3 axes and passed. No mounting detachment occurred. Application Recommended size for the adhesive tapes is 1.18 x 1.18 inches. Application of the tapes is a matter of peeling the release liners and attaching to the MFP and circuit board respectively. See Chomeric’s data sheets and application notes for details. The T404 material does require higher application pressure. The T1680 material is specifically made for low pressure attachment of hybrids, ceramic and flat packages. Removal Refer to Chomeric’s application notes for Thermattach Tape. Specifications Refer to Table 5: Chomeric Material Specifications for thermal conductivity, temperature range and out-gassing.

pin FUnctions anD applications Pin 1: enable Fu nCt i o n The MFP provides an enable pin that will allow normal power conversion to occur if left open or unconnected. The ENABLE pin allows remote turn-on and turn-off control of the MFP. Connecting this pin to ground will disable power conversion, resulting in no output voltage and greatly reduced current consumption. The MFP ENABLE function will work with an open collector device connected to the pin or with a logic high voltage from a digital device as long as the logic high voltage is greater than the minimum voltage listed in the specification for enabled operation. The enable pin is active high at > 0.8 V or with a floating input. Sequencing: The start-up of the MFP can be delayed with the addition of an external capacitor connected to the ENABLE pin. This feature is useful in sequencing the start-up of multiple point of load converters in a system requiring a specific startup sequence for various low-voltage loads. The startup delay is roughly equal to 1 millisecond per microfarad of capacitance. More precise external capacitance values can be found in Table 6 where it can be seen that there is a variation in startup delay time as the input voltage varies. The listed delay is from the beginning of application of power to the beginning of internal power conversion. There will be an additional delay as the power converter begins a normal start-up sequence and ramps to final output voltage. Pin 4: synC The MFP includes a synchronization feature, a key capability in low noise system design. The internal conversion oscillator can be synchronized with a system clock or with a bus voltage source. The MFP is designed to synchronize with a 300 kHz system but can be synchronized with sources up to 600 kHz, a frequency range used by many DC/DC converters. A synchronized system prevents the generation of low frequency sub harmonics in the audio range. The synchronization input amplitude can range from 3 VDC to 6 VDC. Figure 17 illustrates the relationship between operating frequency, temperature and input voltage. The external synchronization timing cycle can be varied cycle to cycle for systems employing spread-spectrum clocking or for slave sharing clock interleaving. The DC level of the sync pin (pin 4) can be used to detect the state of the input voltage protection switch.

pin FUnctions anD applications Pi n s 2 a n d 3: +Vin a n d Vin CoM Mo n Input Voltage The input voltage range for normal operating conditions is 3.0 to 6.0 VDC (Figure 6). For input ripple current see page 17, Figures 10 and 11. The VIN Common pin is connected to V OUT Common and case ground. The input and output should share the same ground plane in the power system design. ad d i t i o n a l inPu t bl oCk Fe a t u r e s Input Under and Over Voltage Protection The MFP includes a solid state switch on the input section. This switch opens for fault conditions including input voltages below the minimum and transient voltages above the maximum. The safe operating range includes ground and extends to 8.5 VDC indefinitely and up to 15 volts as a time limited transient. The switch will only close when certain internal conditions are met, including the proper operation of the internal housekeeping supply and a safe input voltage range. No Single Point Failure The solid state switch (SSS) can be used to provide one additional level of reliability: “no single point failure” will result in a connection from input voltages to output loads. The SSS can be opened by grounding of the ENABLE Pin. The status of the SSS can be determined by detecting the voltage on the SYNC pin. A logic low on this pin indicates that the SSS is open. No External Bias Required An internal housekeeping supply that is active at inputs as low as 2 VDC provides a boosted and regulated voltage supply for internal use. This internal supply is one of the reasons that this product can provide full power at very high efficiency at input voltages as low as 3 VDC. No external power source or external bias is required. Input Reflected Noise and Inrush Current Limit Substantial input capacitance is included and the input solid state switch previously described is designed to provide associated inrush current limiting. The substantial input capacitance and high SSS provide a “pi” filter configuration that results in very low reflected ripple current. The very low input noise and inrush limiter make the MFP unique among point of load converters. 1.0 4.0 3.0 2.0 6.0 5.0 3.3 3.0 2.5 2.0 1.5 0.8 0.64 8.5 15.0 Input Voltage (V) Safe Input, Output Disabled 2.75 4.25 3.3 Under Voltage Shutdown 3.4 1.6 1.0 0.5 Operating Input Output Voltage (V) Safe Input, Output Shutdown Region Fi g u r e 6: inPu t Vo l t a g e Vs Ma x iMuM ou tPu t Vo l t a g e Crane Aerospace & Electronics Power Solutions maximum Flexible power (mFp) single output point of load tecHnical preview: mFp0507s, 3 to 6 vDc in, 7 amp, Dc/Dc converter Page 13 of 19www.craneae.com/interpoint MFP0507S Technical Preview Rev D - 2010.11.18 Technical Preview: Contains preliminary information

Up to 0.3 volts of power line drop can be accommodated. If the SENSE pin lead is not connected to the output positive power pin, the output will rise a total of 0.4 volts. The output voltage can be margined upward from the preset value as much as 0.2 volts by the addition of a resistor between the positive SENSE pin and the output power pin. The amount of increase in the output voltage by margining will reduce the available remote sense range by the same amount. The sum of margined voltage and voltage sense drop must be less than 0.2 volts. Sense margining can be used to adjust V OUT from 3.3 to 3.5. Connections must be made as close as possible to Common and to Rx. This method uses the SENSE pin’s voltage compensation function to raise the output voltage. Therefore, there will not be an option to compensate for voltage drop at the load. If connections have no voltage drop, the formula for the resistor is R x = 1000 in ohms (0.2697) (VOUT - 3.3) -1[ ] TRIM A Pin 7 TRIM B Pin 8 OUT COM Pin 9 +VOUT Pin 10 SENSE Pin 5 Rx OU V V T Fi g u r e 7: sense Pin Vo l t a g e Ma r g i n i n g, Vout Fr oM 3.3 t o 3.5 1, 2 Figure 7, Notes: 1.

pin FUnctions anD applications Pin 6: share The MFP includes a current share feature that allows multiple units to operate as a single supply capable of providing a total current that is the sum of the maximum from each of the units that are operated in parallel. In connecting units in parallel, the SHARE pin is connected between units and all but one unit, the master, will have TRIM A and TRIM B pins tied to the positive SENSE pin. The master will have the TRIM pins configured for the desired output voltage while the other units in parallel will match the current and voltage of the master unit. The SHARE pin can be used as an output current monitor because the voltage on this pin is proportional to unit current. See page 11, Figure 4, callout 5. The SHARE pin can be used to drive an MFP as a voltage controlled current source where the output current will be proportional to the applied voltage with an offset. Output currents corresponding to SHARE pin voltages are shown in Figure 16: SHARE as Monitor for Output Current. Connections for current monitoring are also shown in Figure 4. Two connections are critical to sharing between two units. The SHARE pins of the two (or more) units must be tied together and the TRIM A and TRIM B outputs must be tied together and shorted to +Vout and SENSE for each unit that is not the Master. The master unit will be the one with the highest pre-set output voltage. In the case of Figure 8, callout 3, the master is configured with both TRIM pins open for a 0.8 V output. + V IN EN V IN COM SYNC IN SENSE SHARE +V OUT V OUT COM TRIM B TRIM A MFP Single POL Converter MASTER + V IN EN V IN COM SYNC IN SENSE SHARE +V OUT V OUT COM TRIM B TRIM A MFP Single POL Converter SLAVE V IN DC System Clock DC/DC Converter + LO AD — + V IN V IN COM SYNC IN SYNC OUT INHIBIT +V OUT V OUT COM Fi g u r e 8: tyPiCa l sh a r e Co n n eCt i o n w i t h oPt i o n a l sy nC For more information: Pin 1, ENABLE section Pin 4, SYNC section Pins 7 and 8, SHARE section above Crane Aerospace & Electronics Power Solutions maximum Flexible power (mFp) single output point of load tecHnical preview: mFp0507s, 3 to 6 vDc in, 7 amp, Dc/Dc converter Page 15 of 19www.craneae.com/interpoint MFP0507S Technical Preview Rev D - 2010.11.18 Technical Preview: Contains preliminary information

pin FUnctions anD applications Pi n s 7 a n d 8: triM a a n d triM b Output Voltage Set and Adjustment The MFP0507S, single output model has the flexibility to be set for any voltage from 0.64 to 3.3 VDC. The MFP includes five precision set-points that can be accomplished with pin connections alone and no trim resistor. An open circuit on both TRIM pins results in a 0.80 VDC output, grounding one or the other or both pins results in precise output voltages of 1.6 VDC, 2.5 VDC or 3.3 VDC. One other preset voltage is possible using the SENSE pin (pin 5). Connecting both trim pins to the positive SENSE pin results in 0.64 VDC. In-between values of output voltage can be set with the use of external trim resistors in series with the trim pins to ground. Any voltage intermediate to the pre-set voltages is available by adding a trim resistor between Common and both TRIM pins. Table 7 lists available pin-configurable and adjust/trim output voltages.
