DESCRIPTION

The TPS53219A is

Built-In LDO Linear Voltage Regulator

a small-sized single buck

Auto-Skip Eco-mode™ for Light-Load

controller with adaptive on-time D-CAP™ mode

control. The device is suitable for low output voltage,

high current, PC system power rail and similar

point-of-load (POL) power supplies in digital

consumer products. The small package and minimal

pin-count save space on the PCB, while the

dedicated EN pin and pre-set frequency selections

simplify the power supply design. The skip-mode at

light load conditions, strong gate drivers and low-side

FET R_DS(on)current sensing supports low-loss and

high efficiency, over a broad load range. The

conversion input voltage (high-side FET drain

voltage) range is between 4.5 V and 25 V, and the

output voltage range is between 0.6 V and 5.5 V. The

TPS53219A is available in a 16-pin, QFN package

specified from –40°C to 85°C.
