MCP16311/2
30V Input, 1A Output, High-Efficiency,
Integrated Synchronous Switch Step-Down Regulator
Features General Description 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
protection. The MCP16311/2 provides all the active
functions for local DC-DC conversion, with fast transient
response and accurate regulation. Up to 95% Efficiency
