3 Description

The TPS53820 device is D-CAP+ mode integrated

step-down converter for low current SVID rails of Intel

CPU power supply. It provides up to two outputs to

power the low current SVID rails such as VCCANA

(5.5 A) and P1V8 (4 A). The device employs D-CAP+

mode control to provide fast load transient

performance. Internal compensation allows ease of

use and reduces external components.

The device also provides telemetry, including input

voltage, output voltage, output current and

temperature reporting. Over voltage, over current and

over temperature protections are provided as well.

The TPS53820 device is packaged in a thermally

enhanced 35-pin QFN and operates between –40°C

and 125°C.
