TPS51215A

SLUSDW9A –JUNE 2020–REVISED JUNE 2020

TPS51215A Single Phase, D-CAP2 Controller with 2-Bit VID Control

and Low Power Mode

1 Features

3 Description

The TPS51215A is

a single-phase, D-CAP2™

•

Differential voltage feedback

synchronous buck controller with a 2-bit VID input

supporting and three other independent

•

DC compensation for accurate regulation

Wide input voltage range: 3 V to 28 V

externally programmable output voltage levels, where

full external programmability of the voltage level, step

setting and voltage-change slew rate is desired. It is

used for Intel IMVP8/9 applications where multiple

voltage levels are desired.

Flexible, 2-bit VID supports output voltage from

0.5-V to 2.0-V and 0-V V_OUT

•

D-CAP2™ mode at 600kHz for Ultra-Low/Low

ESR Output Capacitor

The TPS51215A supports all POS/SPCAP and/or all

ceramic MLCC output capacitor options in

applications where remote sense is a requirement.

Tight DC load regulation is achieved through external

programmable integrator capacitor. The TPS51215A

provides full protection suite, including OVP, OCL, 5-

V UVLO and thermal shutdown. It supports the

conversion voltage up to 28 V, and output voltages

adjustable from 0.5 V to 2 V.

•

4700 ppm/°C, low-side R_DS(on)current sensing

Programmable soft-start time and output voltage

transition time

•

Built-in output discharge

Power good output

Integrated boost switch

Built-in OVP/UVP/OCP

Thermal shutdown (non-latched)

3-mm × 3-mm, 20-Pin, QFN (RUK) package

The TPS51215A is available in the 3 mm × 3 mm,

QFN, 0.4-mm pitch package and is specified from

–40°C to 125°C.
