MIC2182 Datasheet High-efficiency Synchronous Buck Controller

Manufacturer: Microchip Technology

Overview: MIC2182 High-Efficiency Synchronous Buck Controller.

General Description

The MIC2182 is a synchronous buck (step-down) switching regulator controller.

An all N-channel synchronous architecture and powerful output drivers allow up to a 20A output current capability.

The PWM and skip-mode control scheme allows efficiency to exceed 95% over a wide range of load current, making it ideal for battery powered applications, as well as high current distributed power supplies.
