DESCRIPTION
The SP6 36 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 con -
version from 5V to 24V. The SP6 36 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 SP6 36
is available in a space saving 6-pin QFN and offers excellent thermal performance.
