Texas Instruments  TPS53627RSMT

The TPS53627 device is a driverless, VR13 SVID compliant, synchronousbuck controller. Advanced control features such as D-CAP+™architecture with overlapping pulse support undershoot reduction (USR) and overshootreduction (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 efficiencyboost. The device integrates a full set of VR13 I/O features including VR_READY (PGOOD),ALERT and VR_HOT. The SVID interface address allowsprogramming from 00h to 07h. Adjustable control of VOUT slew rate can beprogrammed 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 enhanced32-pin VQFN package that operates from –40°C to +105°C.
