RT8011/A
2A, 4MHz, Synchronous Step-Down
Regulator
General Description
The RT8011/A is a high efficiency synchronous, step-down DC/DC converter.
Its input voltage range is from 2.
6V to 5.
5V and provides an adjustable regulated output voltage from 0.
8V to 5V while delivering up to 2A of output current.
The internal synchronous low on-resistance power com switches increase efficiency and eliminate 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.
Current mode operation with external compensation allows ...
