DESCRIPTION  
The SP7655 is a synchronous step-down switching regulator optimized for high efficiency. The part is designed to be  
especially attractive for dual supply, 12V or 24V distributed power systems step down with 5V used to power the  
controller.ThislowerVCC voltageminimizespowerdissipationinthepartandisusedtodrivethetopswitch.TheSP7655  
is designed to provide a fully integrated buck regulator solution using a fixed 300kHz frequency, PWM voltage mode  
architecture. Protection features include UVLO, thermal shutdown and output short circuit protection. The SP7655 is  
available in the space saving DFN package.
