UPM SERIES - NON-ISOLATED, 40 WATT

FEATURES

UPM non-isolated DC/DC buck converters deliver high

power and excellent transient response in a compact

1.0” x 2.0” x 0.475” package. The UPM can provide up

to 40 Watts of output power at 12A output current, and

output voltages from 1.2 to 3.3V.

Featuring open-

frame, 100% surface-mount construction and high

efficiency, the UPM excels in difficult thermal

environments.
