Description

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.
