The RT8071A is a high efficiency synchronous, step-down DC-DC converter. Its input voltage ranges from 2.7V to 5.5V that provides an adjustable regulated output voltage from 0.6V to V<sub>IN</sub> 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 compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The RT8071A is available in a WDFN-10L 3x3 package.
