RT6237B Datasheet | Richtek

® RT6237A/B 7A, 18V, 500kHz, ACOTTM Synchronous Step-Down Converter General Description The RT6237A/B is a high-performance 500kHz, 7A stepdown regulator with internal power switches and synchronous rectifiers. It Features quick transient response using its Advanced Constant On-Time (ACOTTM) control architecture that provides stable operation with small ceramic output capacitors and without plicated external pensation, among other benefits. The input voltage range is from 4.5V to 18V and the output is adjustable from 0.7V to 8V. The proprietary ACOTTM control improves upon other fast response constant on-time architectures, achieving nearly constant switching frequency over line,...
