Fixed 300-kHz (TPS51113) and 600-kHz
(TPS51163) switching frequency. The overcurrent
(TPS51163) Switching Frequency
(OC) protection employs the low-side RDS(on) current
sensing and has user-programmable threshold. The
UV/OV Protections and Power Good Indicator
OC threshold is set by the resistor from LDRV_OC
Internal Soft-start
pin to GND. The resistor value is read when the
Integrated High-Current Drivers Powered by
over-current programming circuit applies 10

VDD
current to the LDRV_OC pin during the calibration
phase of the start-up sequence.

Server and Desktop Computer Subsystem
The integrated gate driver is directly powered by
Power Supplies (MCH, IOCH, PCI, Termination)
VDD. VDD can be connected to VIN in some

applications.
The

to achieve higher efficiency. An adaptive anti-cross
conduction scheme is used to prevent shoot-through
between the power FETs.
