描述 Description

The MCP16311 is a compact, high-efficiency, fixed?frequency PWM/PFM, synchronous step-down DC-DC converter?in a 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 provides all the active?functions for local DC-DC conversion, with fast?transient response and accurate regulation.
