MaxLinear | SP6134EB

Exar's PowerXR products fuse digital power-supply control and monitoring technology with high-performance analog circuitry in a new generation of digital power-management products that enable system architects to create products with advanced, integrated, switching power supplies that significantly reduce wasted energy compared to more commonly used linear power-supply regulators.

The SP6134 is a synchronous step-down switching regulator controller optimized for high efficiency. The part is designed to be especially attractive for dual supply, 12 V step down with 5 V 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 600 kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown and output short circuit protection. The SP6134 is available in the cost and space saving 10-pin MSOP.The SP6134EB is designed with a very accurate 1.0% reference over line, load and temperature.
