RT8290 - Richtek

RT8290 340kHz Synchronous Step-Down Converter

The RT8290 is a high efficiency synchronous step-down DC/DC converter that can deliver up to 3A output current from 4.5V to 23V input supply. The RT8290's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by-cycle current limit provides protection against s.
