[Type text] [Type text] [Type text] February 16 -2018 A.01 HB300 Series of Half-Brick Wide Input Range 180 to 425 Volts Up to 150 Watts DC -DC Converter Operating Temperature Range This HB300 series of converters is rated to operate over a wide case temperature range of - 40°C to +100°C. Consideration must be given to the de-rating curves when ascertaining maximum power that can be drawn from the converter. The maximum power drawn from half brick models is influenced by usual factors, such as:
- Input voltage range
- Output load current
- Forced air or natural convection
- Heat Sink Output Voltage Adjustment The output voltage for the on HB300 series outputs of 5 , 12 and 24 Volts models is adjustable within the range of +10% to – 20%. Over Current Protection The converter is protected against over current or short circuit conditions. At the instance of current- limit inception, the module enters a hiccup mode of operation, whereby it shuts down and automatically attempts to restart. While the fault condition exists, the module will remain in this hiccup mode, and can remain in this mode until the fault is cleared. The unit operates normally once the output current is reduced back into its specified range. Output over Voltage Protection The output overvoltage protection consists of an internal circuit that limits the output voltage. If more accurate output over voltage protection is required , then an external circuit can be used via the remote on/off pin. Note: Please note that device inside the power supply might fail when voltage more than rate output voltage is applied to output pin. This could happen when the customer tests the over voltage protection of unit. Remote On/Off The On/Off input pin permits the user to turn the power module on or off via a system signal. Two remote on/off options are available. Positive logic turns the module on during a logic high voltage on the On/Off pin, and off during a logic low. The O n/Off pin is internally pulled up through a resistor. A properly de -bounced mechanical switch, open c ollector transistor, or FET can be used to drive the input of the On/Off pin. If not using the remote on/off feature, leave the On/Off pin open. Models with part number suffix “N” are the “negative logic” remote on/off version. The unit turns off if the remote on/off pin is high (>3.5Vdc or open circuit). The converter turns on if the on/off pin input is low (<1.8Vdc). Note that the converter is off by default. UVLO (Under Voltage Lock Out) Input under voltage lockout is standard with this converter. At input voltages below the input under voltage lockout limit, the module operation is disabled. The unit will operate when the input voltage goes above the upper threshold. Over Temperature Protection These modules have an over temperature protection circuit to safeguard against thermal damage. When the case temperature rises above over temperature shutdown threshold, the converter will shut down to protect it from overheating. The module will automatically restart after it cools down. Shutdown occurs with the maximum case reference temperature is exceeded. Please measure case temperature of the center part of aluminum baseplate. Recommended Layout, PCB Footprint and Soldering Information The user must ensure that other components and metal in the vicinity of the converter meet the spacing requirements to which the system is approved. Low resistance and low inductance PCB layout should be used where possible. Proper attention must also be given to low impedance tracks between power module, input and output grounds. Clean the soldered side of the module with a brush, Prevent liquid from getting into the module. Do not clean by soaking the modu le into Logic State (Pin 2) Negative Logic Positive Logic Logic Low – Switch Closed Module on Module off Logic High – Switch Open Module off Module on Page 5 of 18

Do not allow solvent to come in contact with product labels or resin case as this may changed the color of the resin case or cause deletion of the letters printed on the product label. After cleaning, dry the modules well. The suggested soldering iron is 450 ℃ for up to 5seconds(less than 50W). Furthermore, the recommended soldering profile and PCB layout are shown below. The recommended footprints and soldering profiles are shown in the next two figures. Note： 1. Soldering Materials: Sn/Cu/Ni 2. Ramp up rate during preheat: 1.4 ℃ /Sec (From 50 ℃ to 100℃) 3. Soaking temperature: 0.5 ℃ /Sec (From 100 ℃ to 130℃), 60±20 seconds 4. Peak temperature: 260 ℃, above 250℃ 3~6 Seconds 5. Ramp rate during cooling: - 10.0 ℃/Sec (From 260 ℃ to 150℃) Convection Requirements for Cooling To predict the approximate cooling needed for the half brick module, refer to the power de- rating curves in the next section These de-rating curves are approximations of the ambient temperatures and airflows required to keep the power module temperature below its maximum rating. Once the module is assembled in the actual system, the module’s temperature should be monitored to ensure it d oes not exceed 100°C as being measured at the center of the top of the case (thus verifying proper cooling). Thermal Considerations The power module operates in a variety of thermal environments; however, sufficient cooling should be provided to help ensur e reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. The test data is presented in the next section . The power output of the module should not be allowed to exceed rated power (V o_set x Io_max). Connection for standard use The connection for standard use is shown below. An external input capacitor (C1) 180uF for all models is recommended to reduce input ripple voltage. External output capacitors (C2, C3) are recommended to reduce outpu t ripple and noise, 5Vout with 47uF T521 KO CAP. <55mR and 1uF ceramic capacitor, 48Vout with 10uF aluminum capacitor and 1uF ceramic capacitor and other modes with 10uF tantalum capacitor and 1uF ceramic capacitor for other models. Note: If the impedance of input line is high, C1 capacitance must be more than above. Use more than two recommended capacitor above in parallel when ambient temperature becomes lower than - 20 ℃. Input Capacitance at the Power Module The convert ers must be connected to low AC source impedance. To avoid problems with loop stability source inductance should be low. Also, the input capacitors (Cin) should be placed close to the converter input pins to decouple distribution inductance. However, the external input capacitors are chosen for suitable ripple handling capability. Low ESR capacitors are good choice. Circuit as shown as below represents typical measurement methods for reflected ripple current. C1 and L1 simulate a typical DC source impedance. The input reflected-ripple current is measured by current probe to oscilloscope with a simulated source Inductance (L1).

C3: 1uF/ 1210 ceramic capacitor Output Voltage Adjustment Output may be externally trimmed ( -20% to +10%) with a fixed resistor or an external trim -pot as shown (optional). Model specific formulas for calculating trim resistors are available upon request as a separate document Output voltage trim circuit configuration In order to trim the voltage up or down, one needs to connect the trim resistor either between the trim pin and -Vo for trim -up or between trim pin and +Vo for trim-down. The output voltage trim range is ±10%. This is shown in the figure below Output voltage trim up circuit Output voltage trim down circuit The recommend Resistor Values: For Vo=5V R trim_up is defined as : For others R trim_up decision: Where: 1- R trim_up is the external resistor in KΩ. 2- V o_nom is the nominal output voltage. 3- Vo is the desired output voltage. 4- R1, R2, R3 and V r are internal components. For example: to trim -up the output voltage of the HB300S 5-60 module by 5% to 5.25 V, R trim_up is calculated as follows: Vo – Vo_nom = 5.25 – 5 = 0.25V R1 = 2.32KΩ, R2 = 1.8 K Ω , R3 = 0KΩ, Vr= 2.5 V, Vf=0.5 V On the other hand, R trim_down is defined as: Where: 1- R trim_down is the external resistor in K Ω. 2- V o_nom is the nominal output voltage 3- Vo is the desired output voltage. %100. ×−= LL LLHL V VVregLine Vout (V) R1 (KΩ) R2 (KΩ) R3 (KΩ) VR (KΩ) Vf (KΩ) 5 2.32 1.8 0 2.5 0 12 9.1 24 5.1 2.5 0.50 24 20 68 7.5 2.5 0.50 28 23.7 82 6.2 2.5 0.50 48 36 82 5.1 2.5 0.50 Page 11 of 18

This feature moves the effective output voltage regulation point from the output of the unit to the point of connection of the remote sense pins. This feature automatically ad justs the real output voltage of the HB300 series in order to compensate for voltage drops in distribution and maintain a regulated voltage at the point of load. The remote- sense voltage range is: [(+V out) - (-Vout)] – [(+Sense) – (-Sense)] ≦ 10% of Vo_nominal When remote sense is in use, the sense should be connected by twisted-pair wire or shield wire. If the sensing patterns short, heave current flows and the pattern may be damaged. Output voltage might become unstable because of impedance of wirin g and load condition when length of wire is exceeding 400mm. This is shown in the schematic below: If the remote sense feature is not to be used, the sense pins should be connected locally. The +Sense pin should be connected to the +Vout pin at the module and the - Sense pin should be connected to the -Vout pin at the module. This is shown in the schematic below : Note: Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When u sing remote sense and trim, the output voltage of the module can be increased and consequently increase the power output of the module if output current remains unchanged . Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = V o,set x Io,max) Output Ripple and Noise Output ripple and noise measured with 47uF T521 KO CAP. <55mR and 1uF ceramic capacitor across output for 5Vout, 10uF aluminum capacitor and 1uF ceramic capacitor across output for 48Vout and with 10uF tantalum capacitor and 1uF ceramic capacitor for other models. A 20 MHz bandwidth oscilloscope is normally used for the measurement. The conventional ground clip on an oscilloscope probe should never be used in this kind of measurement. This clip, when placed in a field of radiated high frequency energy, acts as an antenna Trim Up Value % Vo=5V R trim_up Vo=12V R trim_up Vo=24V R trim_up Vo=28V R trim_up Vo=48V R trim_up Trim Down Value % Vo=5V R trim_down Vo=12V R trim_down Vo=24V R trim_down Vo=28V R trim_down Vo=48V R trim_down Page 12 of 18

The noise pickup is eliminated by pressing scope probe ground ring directly against the - Vout terminal while the tip contacts the +Vout terminal. This makes the s hortest possible connection across the output terminals. Output Capacitance For good transient response, low ESR output capacitors should be located close to the point of load. PCB design emphasizes low resistance and inductance tracks in consideration of high current applications. Output capacitors with their associated ESR values have an impact on loop stability and bandwidth. For absolute maximum value of HB300 series’ output capacitance, please refer to p age 3 Maximum Output Capacitance. For values larger than this, please contact your local DATEL ’s representative. Remote On/Off circuit The converter remote On/Off circuit built -in on input side. The ground pin of input side remote On/Off circuit is –Vin pin. For connection examples, see below: For External connection examples, see below: Series Operation Series operation is possible by connecting the outputs two or more modules. Connection is shown in below. The output current in series connection should be lower than the lowest rate current in each power module. L1, L2: 1.0uH C1, C2, C3: 180uF/450V ESR<0.7 Ω Note: 1. If the impedance of the input line is high then, C1, C2, C3 capacitance must be more than above. Use more than two recommended capacitor above in parallel when ambient temperature becomes lower than - 20 ℃ 2. Recommend Schot tky diode (D1, D2) to be connected across the output of each series connected converter, so that if one converter shuts down for any reason, then the output stage won’t be thermally overstressed. Without this external diode, the output stage of the shut-down converter could carry the load current provided by the other series converters, with its MOSFETs conducting through the body diodes. The MOSFETs could then be overstressed and fail. The external diode should be capable of handling the full load current for as long as the application is expected to run with any unit shut down. Series for ±output operation is possible by connecting the outputs two units, as shown in the schematic below. L1, L2: 1.0uH C1, C2, C3: 180uF/450V ESR<0.7Ω Note: If the impedance of input line is high, C1, C2, C3 capacitance must be more than above. Use more than two recommended capacitor above in parallel when ambient temperature becomes lower than - 20 ℃ Parallel / Redundant operation The HB300 series parallel op eration is not possible. Parallel for redundancy operation is possible by connecting the units as shown in the schematic below. The current of each converter become unbalance by a slight difference of the output voltage. Make sure that the output voltage of units of equal value and the output current from each power supply does not exceed the rate current. Suggest use an external potentiometer to adjust output voltage from each power supply. Page 13 of 18

In order to achieve maximum safety and system protection, always use an input line fuse. We recommended a 5A time delay fuse. It is recommended that the circuit have a transient voltage suppressor diode (TVS) across the input terminal to protect the unit against surge or spike voltage and input reverse voltage as shown below: The external input capacitor C in is required in order for the HB300 series to meet EN61000 -4-4, EN61000-4-5. The HB300 re quires an aluminum capacitor (Nippon Chemi- Con KMG series, 180uF/450V) to connect parallel.
