SYNCHRONOUS BUCK CONTROLLER WITH HIGH-CURRENT GATE DRIVER

FEATURES

DESCRIPTION

•

Flexible Power Rails: 5 V to 12 V

Reference: 800 mV ± 0.8%

Voltage Mode Control

The TPS51113 and TPS51163 are cost-optimized,

feature rich, single-channel synchronous-buck

controllers that operates from a single 4.5-V to 13.2-V

supply and can convert an input voltage as low as

1.5 V.

Support Pre-biased Startup

Programmable Overcurrent Protection with

Low-Side R_DS(on)Current Sensing

The controller implements voltage mode control with

fixed 300-kHz (TPS51113) and 600-kHz

•

Fixed 300-kHz (TPS51113) and 600-kHz

(TPS51163) Switching Frequency

(TPS51163) switching frequency. The overcurrent

(OC) protection employs the low-side R_DS(on)current

sensing and has user-programmable threshold. The

OC threshold is set by the resistor from LDRV_OC

pin to GND. The resistor value is read when the

over-current programming circuit applies 10 µA of

current to the LDRV_OC pin during the calibration

phase of the start-up sequence.

•

UV/OV Protections and Power Good Indicator

Internal Soft-start

Integrated High-Current Drivers Powered by

VDD

•

10-Pin 3 × 3 SON Package

The TPS51113/TPS51163 also supports output

pre-biased startup.

APPLICATIONS

•

Server and Desktop Computer Subsystem

Power Supplies (MCH, IOCH, PCI, Termination)

Distributed Power Supplies

General DC-DC Converters

The strong gate drivers with low deadtime allow for

the utilization of larger MOSFETs to achieve higher

efficiency. An adaptive anti-cross conduction scheme

is used to prevent shoot-through between the power

FETs.
