RT5785B
Overview
The RT5785A/B is a high-performance, Advanced Constant On-Time (ACOTTM) monolithic synchronous step-down DC-DC converter that can deliver up to 2A output current from a 2.5V to 6V input supply. The proprietary ACOT control architecture features quick transient response and provides stable operation with small ceramic output capacitors and without complicated external compensation.
