FEATURES

■ User-selectable outputs: 0.75-5V (D12 models) or 0.75-3.3V (W3 models) ■ 6, 10 or 16A maximum output current ■ Double lead free to RoHS standards ■ Selectable phased start-up sequencing and tracking ■ Wide range VIN 8.3-14V or 2.4-5.5V ■ Up to 52 Watts total output power ■ Very high effi ciency up to 95% ■ Starts up into pre-biased load ■ Fast settling, high di/dt IOUT slew rate PRODUCT OVERVIEW These miniature point-of-load (POL) switching DC/DC converters are ideal regulation and supply elements for distributed power and intermedi- ate bus architectures. Fully compatible with the Distributed-power Open Standards Alliance specifi cation (www.dosapower.com), LSN2’s can power CPU’s, programmable logic and mixed- voltage systems with little heat and low noise. A typical application uses a master isolated 12 or 5Vdc supply and individual LSN2 converters for local 1.8 and 3.3Vdc supplies. All system isolation resides in the central supply, leaving lower cost POL regulation at the load. The LSN2’s can deliver very high power (to 52 Watts) in a tiny area with- out heat sinking or external components. They feature quick transient response (to 25μsec) and very fast current slew rates (to 20A/μsec). Typical Unit Ḥ

All capacitors are low ESR types. These capacitors are necessary to accommodate our test equipment and may not be required to achieve specifi ed performance in your applications. All models are stable and regulate within spec under no-load conditions. General conditions for Specifi cations are +25°C, V IN = nominal, VOUT = nominal, full load. “Nominal” output voltage is +5V for D12 models and +3.3V for W3 models. (2) Input Back Ripple Current is tested and specifi ed over a 5-20MHz bandwidth. Input fi ltering is CIN = 2 x 100μF tantalum, CBUS = 1000μF electrolytic, LBUS = 1μH. (3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher temperatures and/or lower airfl ow, the DC/DC converter will tolerate brief full current outputs if the total RMS current over time does not exceed the derating curve. (4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fi xed conditions, TPCBOARD = +25°C, full output load, natural air convection. (5) The On/Off Control may be driven with external logic or by applying appropriate external voltages which are referenced to –Input Common. The On/Off Control Input should use either an open collector/open drain transistor or logic gate which does not exceed +VIN. A 68K/g58 external pullup resistor to +VIN will cause the “ON” state for negative logic models. (6) Short circuit shutdown begins when the output voltage under increasing load degrades approxi- mately 2% from the selected setting. (7) If Sense is connected remotely at the load, up to 0.5 Volts difference is allowed between the Sense and +VOUT pins to compensate for ohmic voltage drop in the power lines. A larger voltage drop may cause the converter to exceed maximum power dissipation. (8) Output noise may be further reduced by adding an external fi lter. See I/O Filtering and Noise Reduction. (9) All models are fully operational and meet published specifi cations, including “cold start” at –40°C. VOUT is nominal. (10) Regulation specifi cations describe the deviation as the line input voltage or output load current is varied from a nominal midpoint value to either extreme. (11) Other input or output voltage ranges are available under scheduled quantity special order. (12) Maximum PC board temperature is measured with the sensor in the center. (13) Do not exceed maximum power specifi cations when adjusting the output trim. (14) When Sequencing is not used, the Power Good output is TRUE at any time the output is within approximately ±10% of the voltage set point. Power Good basically indicates if the converter is in regulation. Power Good detects Over Temperature if the PWM has shut down due to OT. Power Good does not directly detect Over Current. If Sequencing is in progress, Power Good will falsely indicate TRUE (valid) before the output reaches its setpoint. Ignore Power Good if Sequencing is in transition. (15) The maximum output capacitive loads depend on the the Equivalent Series Resistance (ESR) of the external output capacitor. (16) Do not use Pre-bias startup and sequencing together. See Technical Notes below. (17) After short circuit shutdown, if the load is partially removed such that the load still exceeds the overcurrent (OC) detection, the converter will remain in hiccup restart mode. (18) For best noise performance, leave the Track/Sequence pin OPEN when not used.

Solutions To improve start up, review the conditions above. One of the better solutions is to place a moderate size capacitor very close to the input terminals. You may need two parallel capacitors. A larger electrolytic or tantalum cap sup- plies the surge current and a smaller parallel low-ESR ceramic cap gives low AC impedance. Too large an electrolytic capacitor may have higher internal impedance (ESR) and/or lower the start up slew rate enough to upset the DC/ DC’s controller. Make sure the capacitors can tolerate refl ected switching cur- rent pulses from the converter. The capacitors will not help if the input source has poor regulation. A converter which starts successfully at 3.3 Volts will turn off if the input voltage decays to below the input voltage theshold, regardless of external capacitance. Increase the input start up voltage if possible to raise the downward voltage spike. Also, make sure that the input voltage ramps up in a reasonably short time (less than a few milliseconds). If possible, move the input source closer to the converter to reduce ohmic losses in the input wiring. Remember that the input current is carried both by the wiring and the ground plane return. Make sure the ground plane uses adequate thickness copper. Run additional bus wire if necessary. Any added output capacitor should use just enough capacitance (and no more) to reduce output noise at the load and to avoid marginal thresh- old noise problems with external logic. An output cap will also “decouple” inductive reactance in the load. Certain kinds of electronic loads include “constant current” characteristics which destabilize the output with insuf- fi cient capacitance. If the wiring to the eventual load is long, consider placing this decoupling cap at the load. Use the Remote Sense input to avoid ohmic voltage drop errors. An elegant solution to start up problems is to apply the input voltage with the Remote On/Off control fi rst in the off setting (for those converters with an On/Off Control). After the specifi ed start-up delay (usually under 20 mSec), turn on the converter. The controller will have already been stabilized. The short delay will not be noticed in most applications. Be aware of applications which need “power management” (phased start up). Finally, it is challenging to model some application circuits with absolute fi delity. How low is the resistance of your ground plane? What is the inductance (and distributed capacitance) of external wiring? Even a detailed mathematical model may not get all aspects of your circuit. Therefore it is diffi cult to give cap values which serve all applications. Some experimentation may be required. Pre-Biased Startup Newer systems with multiple power voltages have an additional problem besides startup sequencing. Some sections have power already partially ap- plied (possibly because of earlier power sequencing) or have leakage power present so that the DC/DC converter must power up into an existing voltage. This power may either be stored in an external bypass capacitor or supplied by an active source. This “pre-biased” condition can also occur with some types of program- mable logic or because of blocking diode leakage or small currents passed The highest temperatures in LSN2 SIPs occur at their output inductor, whose heat is generated primarily by I 2R losses. The derating curves were developed using thermocouples to monitor the inductor temperature and varying the load to keep that temperature below +110°C under the assorted conditions of air fl ow and air temperature. Once the temperature exceeds +115°C (approx.), the thermal protection will disable the converter. Automatic restart occurs after the temperature has dropped below +110°C. As you may deduce from the derating curves and observe in the effi ciency curves on the following pages, LSN2 SIPs maintain virtually constant effi cien- cy from half to full load, and consequently deliver very impressive temperature performance even if operating at full load. Lastly, when LSN2 SIPs are installed in system boards, they are obviously subject to numerous factors and tolerances not taken into account here. If you are attempting to extract the most current out of these units under demand- ing temperature conditions, we advise you to monitor the output-inductor temperature to ensure it remains below +110°C at all times. Start Up Considerations When power is fi rst applied to the DC/DC converter, operation is different than when the converter is running and stabilized. There is some risk of start up diffi culties if you do not observe several application features. Lower output voltage converters may have more problems here since they tend to have higher output currents. Operation is most critical with any combination of the following external factors: 1 – Low initial input line voltage and/or poor regulation of the input source. 2 – Full output load current on lower output voltage converters. 3 – Slow slew rate of input voltage. 4 – Longer distance to input voltage source and/or higher external input source impedance. 5 – Limited or insuffi cient ground plane. External wiring that is too small. 6 – Too small external input capacitance. Too high ESR. 7 – High output capacitance causing a start up charge overcurrent surge. 8 – Output loads with excessive inductive reactance or constant current characteristics. If the input voltage is already at the low limit before power is applied, the start up surge current may instantaneously reduce the voltage at the input terminals to below the specifi ed minimum voltage. Even if this voltage depres- sion is very brief, this may interfere with the on-board controller and possibly cause a failed start. Or the converter may start but the input current load will now drive the input voltage below its running low limit and the converter will shut down. If you measure the input voltage before start up with a Digital Voltmeter (DVM), the voltage may appear to be adequate. Limited external capacitance and/or too high a source impedance may cause a short downward spike at power up, causing an instantaneous voltage drop. Use an oscilloscope not a DVM to observe this spike. The converter’s soft-start controller is sensitive to input voltage. What matters here is the actual voltage at the input terminals at all times. Symptoms of start-up diffi culties may include failed started, output oscil- lation or brief start up then overcurrent shutdown. Since the input voltage is
