Overview

MIC2178 Micrel, Inc.
MIC2178 2.
5A Synchronous Buck Regulator General Description The Micrel MIC2178 is a 200kHz synchronous buck (stepdown) switching regulator designed for high-efficiency, battery-powered applications.
The MIC2178 operates from a 4.
5V to 16.
5V input and features internal power MOSFETs that can supply up to 2.
5A output current.
It can operate with a maximum duty cycle of 100% for use in low-dropout conditions.
It also features a shutdown mode that reduces quiescent current to less than 5µA.
The MIC2178 achieves high efficiency over a wide output current range by operating in either PWM or skip mode.
The operating mode is externally selected, typically by an intelligent sys...
