RT8082

® RT8082 3A, 2MHz, Synchronous Step-Down Converter General Description The RT8082 is a high efficiency synchronous, step-down DC/DC converter. Its input voltage range is from 2.7V to 5.5V and provides an adjustable regulated output voltage from 1V to 5V 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 ripple voltage is easily smoothed-out by small package filtering elements due to a fixed operating frequency of 2MHz. The 100% duty cycle provides low dropout operation extending battery input range 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 RT8082 operates in forced continuous PWM Mode, which minimizes ripple voltage and reduces the noise and RF interference.
