The MIC2182YSM from Microchip Technology is a synchronous buck (step-down) switching regulator controller designed for high-efficiency power conversion. It utilizes an all N-channel synchronous architecture with powerful output drivers, enabling an output current capability of up to 20A. This controller is ideal for battery-powered applications and high-current distributed power supplies due to its efficiency exceeding 95% over a wide load range.
The device operates from a 4.5V to 32V input voltage and features a maximum duty cycle of 86%, suitable for low-dropout conditions. It includes a shutdown mode that reduces quiescent current to as low as 0.1µA. The MIC2182YSM automatically switches between PWM and skip modes to maintain high efficiency across varying load currents. Skip-mode operation reduces no-load supply current from 1.6mA to 600µA.
Key electrical specifications include a 300kHz oscillator frequency, current-mode control with cycle-by-cycle current limiting, and frequency foldback overcurrent protection. It also incorporates built-in undervoltage protection and adjustable undervoltage lockout. The controller provides a precision 1.245V reference output with 0.6% total regulation.
The MIC2182YSM is available in a 16-pin SSOP package and operates within a temperature range of -40°C to +85°C. It is designed for surface mount applications.
