MCP1612EV#1: 0.8V, 1.7V, 2.4V, or 3.3V @ 1A; Vout+0.5 ~ 5.5V in

Summary

This Synchronous Buck Evaluation Board features Microchip's 1A 1.4MHz synchronous buck regulator in two buck converter applications.

The first application uses the MCP1612 in the 8-leaded MSOP package. This converter has four (0.8V, 1.0V, 1.2V, and 1.4V) selectable output voltages available.

The second application features the MCP1612 in the 8-leaded DFN package. This converter also has four (0.8V, 1.7V, 2.4V, and 3.3V) selectable output voltages. A shutdown terminal is also provided for each converter.

Features:

8-lead MSOP and 8-lead DFN packages for full part evaluation.
Each circuit is capable of delivering 1A of continuous output current.
Seven different output voltages are available.
Shutdown terminal for evaluating startup and shutdown operation.
