MIC2182 Datasheet (Micrel Semiconductor) - High-Efficiency Synchronous Buck Controller

MIC2182, High-Efficiency Synchronous Buck Controller

Micrel’s 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 capabilty.

The PWM and skip-mode control scheme allows efficiency to exceed 95% over a wide range of load current,

MIC2182 Features

* a shutdown mode that reduces quiescent current to 0.1µA. The MIC2182 achieves high efficiency over a wide output current range by automatically switching between PWM and skip mode. Skip-mode operation enables the converter to maintain high efficiency at light loads by turning off circuitry pertainin
