The RT5751A/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 WDFN-6L 2x2 package.
The RT5751A/B adopts Advanced Constant On-Time (ACOT®) control architecture to provide an ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT5751A operate in automatic PSM that maintain high efficiency during light load operation. The RT5751B operate in Forced PWM that help to meet tight voltage regulation accuracy requirements.资料下载
