3 Description

The TPS53627 device is a driverless, VR13 SVID

compliant, synchronous buck controller. Advanced

control features such as D-CAP+ ™architecture with

overlapping

pulse

support

undershoot

reduction

(USR) and overshoot reduction (OSR) to provide fast

transient response, lowest output capacitance and

high efficiency. The device also supports single-

phase operation in CCM and DCM operation for light-

load efficiency boost. The device integrates a full set

of

VR13

I/O

features

including

VR_READY

(PGOOD), ALERT and VR_HOT. The SVID interface

address allows programming from 00h to 07h.

Adjustable

control

of

programmed as high as 20mV/uS.

Paired with the TI NexFET™ Power Stage, this total

solution delivers exceptionally high speed and low

switching loss.

The TPS53627 device package is a space saving,

thermally enhanced 32-pin VQFN package that

operates from –40°C to +105°C.
