The part is designed to be especially attractive for single supply step down conversion from 5V to 24V. The SP6136 is designed to drive a pair of external NFETs using a fixed 600 KHz 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 SP6136 is available in a space saving 16-pin QFN and offers excellent thermal performance.
