MIC2182 Datasheet | Micrel Semiconductor

Micrel High-Efficiency Synchronous Buck Controller General Description 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, making it ideal for battery powered applications, as well as high current distributed power supplies. The MIC2182 operates from a 4.5V to 32V input and can operate with a maximum duty cycle of 86% for use in lowdropout conditions. It also Features a shutdown mode that reduces quiescent current to 0.1µA. The...
