RT5761A Overview
The RT5761A/B is a simple, easy-to-use, 1A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V. The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a UDFN-6L 1.4x1 package. The RT5761A/B adopts Advanced Constant On-Time (ACOT® ) control architecture to provide an ultrafast transient response with few...
