DESCRIPTION

The SP7652 is a synchronous step-down switching regulator optimized for high efﬁciency. The part is designed to

be especially attractive for dual supply, ꢀ2V 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 solu-

tion 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.
