RT8004 Datasheet | Richtek

Description The RT8004 is a high efficiency synchronous, step-down DC/DC converter. Its input voltage range is from 2.65V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V while delivering up to 3A of output current. The internal power switch with 75mΩ on-resistance increases efficiency and eliminates the need for an external Schottky diode. Switching frequency is set by an external .. resistor or can be synchronized to an external clock. 100% duty cycle provides low dropout operation extending battery life in portable systems. External pensation allows the transient response to be optimized over a wide range of loads and output capacitors. The RT8004 operates in Forced Continuous Mode which reduces noise and RF interference. 100% duty cycle in Low Dropout Operation further maximize battery life.
