Beschreibung

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 stepped down with 5V used to power the controller. This lower VCCvoltage minimizes power dissipation in the part and is used to drive the top switch. The SP7655 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
