The MIC2182YM-TR from Microchip Technology is a synchronous buck (step-down) switching regulator controller. It features an all N-channel synchronous architecture with powerful output drivers, enabling an output current capability of up to 20A. The controller utilizes a PWM and skip-mode control scheme to achieve efficiencies exceeding 95% over a wide load current range, making it suitable for battery-powered applications and high-current distributed power supplies.
This device operates within an input voltage range of 4.5V to 32V and can achieve a maximum duty cycle of 86% for low-dropout conditions. It includes a shutdown mode that reduces quiescent current to less than 0.1µA. The MIC2182YM-TR automatically switches between PWM and skip modes to maintain high efficiency at both light and heavy loads. Skip-mode operation reduces no-load supply current from 1.6mA to 600µA.
The MIC2182YM-TR is available in a 16-pin SOIC package and operates within an ambient temperature range of -40°C to +85°C. Its features include current-mode control, cycle-by-cycle current limiting, built-in undervoltage protection, and adjustable undervoltage lockout. The controller also offers frequency foldback overcurrent protection and sustained short-circuit protection.
Key electrical specifications include a 300kHz oscillator frequency and a precision 1.245V reference output with 0.6% total regulation. The controller drives N-channel MOSFETs and has 5 Ohm impedance MOSFET drivers. It is designed for surface mount applications.
