Small 10-Pin MSOP Package
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 V
CC
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
.
