General Description

The RT5701 is a Peak-Current Mode Pulse-WidthModulated (PWM) step-down DC/DC converter with I2C control interface.

Capable of delivering 4A continuing output current over a wide input voltage range from 2.5V to 5.5V, the RT5701 is ideally suited for Automotive Infotainment applications for low-voltage outputs to Micro controllers and ASICs in Navigation, Information Display, and Audio systems, Video systems and other battery operated systems requiring very low Shutdown current and Quiescent current consumption.

Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode.

Overview
