TI TPS65258 Power Management IC

Texas Instruments TPS65258 Power Management IC features three step-down buck converters and two USB switches. This TI PMIC also offers high-side and low-side MOSFETs that are integrated to provide fully synchronous conversion with higher efficiency. The step-down buck converters are designed to simplify an application while also giving the designer the option to optimize their usage according to the target application. TI TPS65258 power management IC can operate in 5, 9, 12, or 15V systems. The integrated USB switches provide up to 1A of current as required by downstream USB devices.
