Microchip Technology, Inc. DC DC Switching Controllers MIC2182-3.3YSM-TR

The MIC2182-3.3YSM-TR is a synchronous buck switching regulator controller designed for high efficiency and high output current applications. It operates with an input voltage range of 4.5V to 32V and can deliver an output voltage of 3.3V with a maximum output current capability of 20A. The device features a PWM and skip-mode control scheme that allows for efficiencies exceeding 95%, making it suitable for battery-powered devices and high-current distributed power supplies. This regulator includes a shutdown mode that reduces quiescent current to 0.1¬µA, and it automatically switches between PWM and skip mode to maintain high efficiency at varying load conditions. The MIC2182-3.3YSM-TR is housed in a 16-pin narrow SSOP package and operates within a temperature range of -40¬8C to +85¬8C. Additional features include cycle-by-cycle current limiting, built-in undervoltage protection, and a precision reference output of 1.245V with 0.6% total regulation. The device is also easily synchronizable and provides sustained short-circuit protection at any input voltage.
