Introduction

AI Translation

The TPS53219A is a small single-phase synchronous buck controller with adaptive on-time D-CAP mode control. It is suitable for low output voltage, high current PC system power rails and similar point-of-load (POL) power supplies in digital consumer products. The compact package and minimal pin count save PCB space, while the dedicated EN pin and preset frequency selection simplify power supply design. Skip mode at light load, robust gate drivers, and low-side FET RDS(on) current sensing support low-loss, high-efficiency operation across a wide load range. The conversion input voltage (high-side FET drain voltage) ranges from 4.5V to 25V, and the output voltage ranges from 0.6V to 5.5V. The TPS53219A is offered in a 16-pin VQFN package with an operating temperature rating of -40°C to +85°C.
