The average input current limit can be programmed by an external resistor. Its input voltage range is from 3V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V while delivering up to 1.2A of output current. The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode. Current mode operation with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The RT8032 is operated in forced continuous PWM Mode which minimizes ripple voltage and reduces the noise and RF interference. The 100% duty cycle in Low Dropout Operation can maximize the battery life.
