RT5753A/B/C/D
3A, 1.2MHz, 6V Synchronous Step-Down Converter In WDFN-8L 2x2
General Description
The RT5753A/B/C/D is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V. The device builds in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in WDFN-8L 2x2 and WDFN-8SL 2x2 packages.
The RT5753A/B/C/D 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 RT5753A/C operates in automatic PSM that maintains high efficiency during light load operation.
