Wide Input Voltage Range 6A, 600kHz, Buck Regulator

The SP7652 is a synchronous step-down switching regulator optimized for high efficiency. The part 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. The SP7652 is designed to provide a fully integrated buck regulator solution

using a fixed 600kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown

and output short circuit protection. The SP7652 is available in the space saving DFN package

.
