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 singlephase

operation in CCM and DCM operation for lightload

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 VOUT slew rate can be

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.
