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.
