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.
