EVB_RT7275GQW

The EVB_RT7275GQW is an evaluation board for RT7275GQW device. The RT7275GQW is a high performance 3A step down regulator with an internal power switch and synchronous rectifier. It features quick transient response using its Advanced Constant On Time (ACOT) control architecture that provides stable operation with small ceramic output capacitors and without complicated external compensation, among other benefits. The input voltage range is from 4.5V to 18V and the output is adjustable from 0.765V to 8V. The proprietary ACOT control improves upon other fast response constant ontime architectures, achieving nearly constant switching frequency over line, load and output voltage ranges. Since there is no internal clock, response to transients is nearly instantaneous and inductor current can ramp quickly to maintain output regulation without large bulk output capacitance. The RT7275GQW is stable with and optimized for ceramic output capacitors.
