RT8068A
RT8068A is Synchronous Step-Down Converter manufactured by Richtek.
Description
The RT8068A is a high efficiency synchronous, step-down DC-DC converter. It's input voltage range from 2.7V to 5.5V that provides an adjustable regulated output voltage from 0.6V to VIN while delivering up to 3A of output current. The internal synchronous low on resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The switching frequency is fixed internally at 1MHz. The 100% duty cycle provides low dropout operation, hence extending battery life in portable systems. Current mode operation with internal pensation allows the transient response to be optimized over a wide range of loads and output capacitors. The RT8068A is available in WDFN-10L 3x3 and SOP-8 (Exposed Pad) packages.
