The SP6132H is a synchronous step-down switching regulator controller optimized for high efficiency. It has a wide input and output voltage range, strong output capability, high integration, and comprehensive protection features. It is suitable for applications with dual power supplies, 12V step-down, and 5V for controller power supply.
The SP6132H is a high‑voltage, 300 kHz synchronous PWM controller designed for step‑down conversion with input voltages from 3 V to 28 V. It drives a pair of external NFETs and includes integrated UVLO, thermal shutdown, and short‑circuit protection.
