MCP16311 - Microchip

MCP16311 Integrated Synchronous Switch Step-Down Regulator

The MCP16311/2 is a compact, high-efficiency, fixed frequency, synchronous step-down DC-DC converter in an 8-pin MSOP, or 2 x 3 TDFN package that operates from input voltage sources up to 30V. Integrated features include a high-side and a low-side switch, fixed frequency peak current mode control, internal compensation, peak current limit and overtemperature.
