Richtek RTQ2822B

Description

The RTQ2822A/B is a high-performance, synchronous step-down converter that can deliver up to 12A output current with an input supply voltage range of 4.5V to 17V. The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode for bootstrap circuit to offer a very compact solution. Switching frequency is selectable in 400kHz, 800kHz and 1200 kHz.
