Description
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.
