ST L6739TR

降压降压4.75V ~ 13.2V

Overview

The L6739TR is a single-phase step-down controller with integrated high current drivers that provides complete control logic and protection to realize a DC-DC converter.

The device flexibility allows to manage conversions with power input VINas low as 1.5 V and the device supply voltage ranging from 5 V to 12 V bus. The L6739TR device features a proprietary algorithm that allows light-load efficiency optimization, boosting efficiency without compromising the output voltage ripple. The integrated 0.8 V reference allows generation of output voltages with ± 0.5% accuracy over line and temperature variations. The oscillator is programmable up to 600 kHz. The L6739TR provides a programmable overcurrent protection and overvoltage protection. The current information is monitored across the inductor DCR. The L6739TR device is available in a VFQFPN 16 - 3 x 3 mm package.
