Description
The SP6139EU is a synchronous step-down switching regulator controller that is optimized for high efficiency. It is designed to be especially attractive for dual supply, 12V step-down with 5V used to power the controller. This lower VCC voltage minimizes power dissipation in the part. It is designed to drive a pair of external NFETs using a fixed 1.3MHz frequency, PWM voltage-mode architecture. Protection features include UVLO, thermal shutdown, and output short circuit protection. The SP6139EU is available in the cost and space-saving 10-pin MSOP.
