The SP6132 is a wide input, 300KHz synchronous PWM 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.
The SP6132 is a wide‑input, 300 kHz synchronous step‑down PWM controller designed for high efficiency in dual‑supply applications. It operates from 3 V to 15 V input and drives external NFETs with up to 30 A output capability in a compact 10‑pin MSOP package.
Key features include programmable soft‑start, UVLO protection for both VCC and VIN, thermal shutdown at 145 °C, and short‑circuit protection with auto‑restart. The device is suited for automotive, industrial, and power‑supply designs, offering flexible compensation options and a high‑bandwidth error‑amplifier.
