1 / 4 page REV. JUN 02, 2004 UPM-EA DC-DC Series Data Sheet Programmable-Output, 45 Watts Page 1 of 4 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. Technical Specifications • 5-bit programmable output • High efficiency topology • Excellent transient response • Power Good signal • Surface-mount construction • Short-circuit protection • Low profile • Water washable Switching Frequency 200 kHz Temperature Coefficient 50ppm/°C Baseplate Operating Temperature 0 to +100°C Storage Range -40 to +100°C Internal Input Capacitance 500 µF Max.
