RT5716 1.8V to 5.5V, 0.6A/1A, 2.3A IQ Step Down Converter 6-Pin, 0.35mm Pitch WCSP Package General Description The RT5716 is a high switching frequency synchronous step-down converter with a quiescent current of 2.3A. The device uses RBCOT (Ripple-Based Constant-OnTime) control to enhance load/line transient response to be optimized over a wide range of loads and output capacitors. The RT5716 input voltage range is from 1.8V to 5.5V, making it suitable for battery applications. It provides 16 selectable output voltage levels by connecting the resistor between RSEL/MODE pin and GND. The PFM design can maintain high efficiency during the light load. At higher load conditions, the device automatically switches to PWM. The device can deliver up to 0.6/1A loading current.
