The DCHBW75 series of DC/DC power converters provides up to 76.8 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 48VDC with 4:1 ultra wide input voltage ranges of 9~36VDC, 18~75VDC and 43~160VDC. Some
features include high efficiency up to 91%, adjustable output voltage, positive remote on/off control, and
under voltage lockout. These converters also have short circuit, over voltage, over load, and over
temperature protection. The DCHBW75 series is RoHS compliant and has UL60950-1, EN60950-1,
IEC60950-1, EN45545-2 and EN50155 safety approvals. Several different options are available for this
series including negative remote on/off, terminal block, pin length, heatsinks, and thru-hole inserts. Please

Typical Value at Nominal Input Voltage and No Load.
Test by minimum input and constant resistive load.
Typical Value at Nominal Input Voltage and Full Load.
Input source impedance: The power module will operate as specifications without external components, assuming that the source voltage has a
very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the power module. An
external input capacitor is recommended for 24VDC nominal input models. We suggest 4.7µF/50V X7R MLCC or Nippon chemi-con KY series,
68µF/100V, ESR 110mΩ or better capacitor. For terminal block versions, the capacitor is included as standard and an external capacitor is not
necessary.
Output voltage is adjustable for 10% trim up or -20% 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 5/6.
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.
The CTRL pin voltage is referenced to –INPUT. To order negative logic remote on/off control add the suffix “R” to the model number.
1. The thermal test conditions for vertical direction are by natural convection (20LFM)
2. Heat sink is optional. See the “Product Options” table for suffix options.
The standard module meets EMI Class A or Class B with external components.
An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. For 24 & 48VDC nominal input models, we
recommend connecting one aluminum electrolytic capacitor (Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ) in parallel. For 110VDc
nominal input models, we recommend connecting three aluminum electrolytic capacitors (Ruby-con BXF series, 100µF/250V) in parallel.
CASE GROUNDING: EMI can be reduced when you connect the four screw bolts to the shield plane.
This series comes with several different options: Negative remote on/off control, heatsinks, pin length, thru-hole inserts, and terminal blocks. See
the “Product Options” table on page 6 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.
