The DCHB200 series of DC/DC power converters provides up to 255 Watts of output power in an industry standard
half-brick package and footprint. This series consists of single output models ranging from 3.3VDC to 53VDC with
2:1 wide input voltage ranges. Some features include high efficiency up to 93%, adjustable output voltage, and
remote on/off control. These converters also have short circuit, over voltage, over current, and over temperature
protection. The DCHB200 series is RoHS compliant and has UL60950-1, EN60950-1, and IEC60950-1 safety approvals.
Several different options are available for this series including negative remote on/off control, terminal block, pin
length, heatsinks, sync pin, case pin, and thru-hole inserts.

NOTES
1. Input Source Impedance: These converters will operate under all listed specifications without external components assuming that the source voltage has
very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the converter. Since real
world voltage sources have finite impedance, performance can be improved by adding an external filter capacitor. We recommend Nippon chemi-con KY
series, 100μF/100V.
2. (1) Multiple DCHB200 series modules can be synchronized together simply by connecting the module SYNC pins together. Care should be taken to
ensure the ground potential differences between the modules are minimized.
(2) In this configuration all of the modules will be synchronized to the highest frequency module.
(3) Up to three modules can be synchronized using this technique.
(4) More relevant information in the application notes.
3. Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used the +SENSE should be connected to its
corresponding +OUTPUT and likewise the -SENSE should be connected to its corresponding –OUTPUT.
4. (1) Thermal test conditions for vertical direction are by natural convection (20LFM).
(2) The iron base-plate dimensions are 19” x 3.5” x 0.063” (the height is EIA standard 2U).
(3) Heat sink is optional. See the “Model Number Setup” table on page 7 for suffix options.
5. The DCHB200 standard models (without assembly options) can only meet EN55022 Class A or Class B with external components added.
6. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. We recommend connecting two aluminum electrolytic
capacitors (Nippon chemi-con KY series, 220μF/100V) in parallel.
7. Output voltage is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting a single resistor between TRIM and +SENSE pins
for trim up or between TRIM and -SENSE pins for trim down. To calculate the value of the resistor RU and RD for a particular output voltage see page 7.
8. CASE GROUNDING: EMI can be reduced when you connect the four screw bolts to the shield plane.
9. This series comes with several different options: negative remote on/off control, heatsinks, case pin, sync pin, pin length, terminal block, and thru-hole
inserts. See the “Model Number Setup” table on page 7 for more ordering information.
CAUTION: This power converter is not internally fused. An input line fuse must always be used.

OUTPUT VOLTAGE ADJUSTMENT
Output is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting an external resistor between the TRIM pin and
either the +SENSE or -SENSE pins. With an external resistor between the TRIM and -SENSE pin, the output voltage set decreases. With an external
between the TRIM and -SENSE pin, the output voltage set point increases. Maximum output deviation is +10% inclusive of remote sense. The
value of the external resistor can be obtained by the equations below. The external TRIM resistor needs to be at least 1/8W resistor.
