General Description

The RT5733 is a step-down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5V to 5.5V.

The output voltage is programmed through an I2C interface and is capable of operating up to 3.4MHz.

Using a proprietary architecture with synchronous rectification, the RT5733 is capable of delivering continuous 3.5A, maintaining that efficiency at load currents as low as 10mA.
