The SP6133 is a synchronous step-down switching regulator controller optimized for high efficiency. The part is designed to be especially attractive for single supply step-down conversion from 5V to 24V. The SP6133 is designed to drive a pair of external NFETs using a fixed 300kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown, output short-circuit protection and overcurrent protection with auto restart. The device also features a PWRGD output and an enable input. The SP6133 is available in a space saving 6-pin QFN and offers excellent thermal performance.
