RT5788B Overview
The RT5788A/B is a simple, easy-to-use, 4A synchronous step-down DC-DC converter with an input supply voltage range of 2.5V to 6V. The device build-in an accurate 0.6V (±1.5%) reference voltage and can operate in 100% duty cycle as a very low dropout voltage regulator. The RT5788A/B integrates low RDS(ON) power MOSFETs to achieve high efficiency and is available in TSOT-23-8 (FC) package.
