Wide Input, 300KHz Synchronous PWM Controller

DESCRIPTION

The SP6132 is wide input, synchronous step-down switching controller 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 SP6132 is designed to drive a pair of external NFETs using a fixed

300kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown and output

short circuit protection. The SP6132 is available in the cost and space saving 10-pin MSOP

.
