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.
