L6731DTR ST DC-DC Controller | 16-PowerTSSOP | 1.5A, 300kHz

Product Overview

The L6731DTR is a high-performance step-down DC-DC controller from STMicroelectronics, designed for low-voltage power supply applications. It integrates a 1.5A gate driver and operates at a fixed 300kHz switching frequency. Housed in a compact 16-PowerTSSOP package (0.173", 4.40mm width), it offers excellent thermal performance and space-saving benefits. The device features a wide input voltage range from 4.5V to 14V and provides an adjustable output voltage down to 0.8V with ±1% accuracy. Protection features include overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown.
