Description
General part information
MIC2182 Series
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 low-dropout conditions. It also 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 pertaining to PWM operation, reducing the no-load supply current from 1.6mA to 600µA. The operating mode is internally selected according to the output load conditions. Skip mode can be defeated by pulling the PWM pin low which reduces noise and RF interference.
