Description: 2.25MHz 1A Synchronous Step-Down Converter

Features

* 2.7V to 5.5V Wide Input Operation Range
* 2.25MHz Fixed-Frequency PWM Operation
* Up to 1A Output Current
* Up to 90% Efficiency
* 0.6V Reference Allows Low Output Voltage
* Internal Soft-Start
* No Schottky Diode Required
* Internal Compensation to Reduce External

Applications

* The RT8057 enters Low Dropout Mode when normal Pulse -Width Mode cannot provide regulated output voltage by continuously turning on the upper P-MOSFET. The RT8057 enters shut-down mode and consumes less than 1μA when the EN pin is pulled low. The switching ripple is easily smoothed-out by small pac
