Description
Features
The UPM-EA programmable DC-DC converter is a high efficiency, step-down converter. The UPM-EA incorporates
a 5-bit DAC output voltage control which is compliant with standard VRM VID Protocol.
The
UPM-EA provides up to 45 watts of output power at 13A output current, and at output voltages from 1.30 to 3.50V.
Featuring open-frame, 100% surface-mount construction and high efficiency topology, the UPM-EA excels in
difficult thermal environments.

Notes
† MTBF predictions may vary slightly from model to model.
†† When used with recommended capacitors
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.
