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 openframe, 100% surface-mount construction and high
efficiency, the UPM excels in difficult thermal
environments.

MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please consult factory
for specific model information.
Units are water-washable and fully compatible with commercial spray or
immersion post wave-solder washing equipment.
