3 Description

The device is a monolithic, 14A, synchronous buck

converter with integrated MOSFETs that enable

high efficiency and offer ease-of-use with minimum

external component count for space-conscious power

systems. The TPS51375H employs D-CAP3 control

mode that provides fast transient response and

excellent line and load regulation with internal

compensation. The ULQ extended battery life feature

is extremely beneficial for long battery life in low

power operation. The large duty operation greatly

improves the load transient performance when input

voltage is low.

Other features include differential remote sensing,

Eco-mode operation for high light load efficiency,

VCC switch-over function for further optimized light

load efficiency, and body braking for load transient

improvement under low output voltage. TPS51375H

supports VCCPRIM_VNNAON power rails in Intel

Meteor Lake and Arrow Lake platform.

The TPS51375H integrates a power-good indicator

and provides an output discharge function. The device

provides complete protection, including OVP, UVP,

OCP, OTP, and UVLO. The device is available in

a 19-pin, 3.0mm × 4.0mm HotRod package, and

the junction temperature is specified from –40°C to

125°C.
