Package: QFN 16 Type

Manufacturer: Texas Instruments


TPS53219A datasheet



The TPS53219A is a small-sized single buck 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.


1. Wide output load range: 0 A to > 20 A

2. Built-in 0.6-V (±0.8%) reference

3. Built-in LDO linear voltage regulator

4. Auto-skip Eco-Mode for light-load efficiency

5. D-CAP mode with 100-ns load-step response

6. Adaptive ON-time control architecture with 8 selectable frequency settings
