UPM-EA DC-DC Series Data Sheet
Programmable-Output, 45 Watts
Features
• 5-bit programmable output
• High efficiency topology
• Excellent transient response
• Power Good signal
• Surface-mount construction
• Short-circuit protection
• Low profile
• Water washable
Description
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.
