MIC2182 Micrel MIC2182 High-Efficiency Synchronous Buck Controller General Description Features Micrels MIC2182 is a synchronous buck (step-down) switch- 4.5V to 32V Input voltage range ing regulator controller. An all N-channel synchronous archi- 1.25V to 6V Output voltage range tecture and powerful output drivers allow up to a 20A output 95% efficiency current capabilty. The PWM and skip-mode control scheme 300kHz oscillator frequency allows efficiency to exceed 95% over a wide range of load Current sense blanking current, making it ideal for battery powered applications, as 5 impedance MOSFET Drivers well as high current distributed power supplies. Drives N-channel MOSFETs 600 A typical quiescent current (skip-mode) The MIC2182 operates from a 4.5V to 32V input and can Logic controlled micropower shutdown (I < 0.1 A) operate with a maximum duty cycle of 86% for use in low- Q Current-mode control dropout conditions. It also features a shutdown mode that Cycle-by-cycle current limiting reduces quiescent current to 0.1 A. Built-in undervoltage protection The MIC2182 achieves high efficiency over a wide output Adjustable undervoltage lockout current range by automatically switching between PWM and Easily synchronizable skip mode. Skip-mode operation enables the converter to Precision 1.245V reference output maintain high efficiency at light loads by turning off circuitry 0.6% total regulation pertaining to PWM operation, reducing the no-load supply 16-pin SOP and SSOP packages current from 1.6mA to 600 A. The operating mode is inter- Frequency foldback overcurrent protection nally selected according to the output load conditions. Skip Sustained short-circuit protection at any input voltage mode can be defeated by pulling the PWM pin low which 20A output current capability reduces noise and RF interference. Applications The MIC2182 is available in a 16-pin SOP (small-outline package) and SSOP (shrink small-outline package) with an DC power distribution systems operating range from 40C to +85C.
