The RPMH-0.5 series is a wide input voltage, 0.5A non-isolated switching regulator power module. The
module accepts with up to 65VDC input and provides a trimmable output from 2.6 up to 28VDC and
comes complete with a full set of features including adjustable output, sequencing, soft-start control, on/
off control, and power good signals. The ultra-compact module has a profile of only 3.75mm, but with an
efficiency of up to 89%, the device can operate at full load in ambient temperatures as high as +95°C
and with power derating up to 105°C without forced air cooling. The package is complete with 6-sided
shielding for optimal EMC performance and excellent heat management.
Notes:
Note4: Output capacitor required. Please

Notes:
Note5: As input approaches output voltage set point, device enters 100% duty cycle mode. In 100% duty cycle mode, Vout equals Vin minus dropout
voltage (refer to
“Dropout Voltage vs. Load“)
Note6: For more detailed information, please refer to
“OUTPUT VOLTAGE TRIMMING“
Note7: Required dropout voltage per 1A output current to be within accuracy (refer to
“Dropout Voltage vs. Load“)
Note8: Measurements are made with a 22µF MLCC across output (low ESR)

OUTPUT VOLTAGE TRIMMING
The RPMH-series offers the feature of trimming the output voltage by using external trim resistors. The values for trim resistors shown in trim tables below are
according to standard E96 values; therefore, the specified voltage may slightly vary. Refer to
