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.The controller implements voltage mode control with a fixed 300-kHz (TPS51113) and 600-kHz (TPS51163) switching frequency. The overcurrent (OC) protection employs the low-side RDS(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. The TPS51113/TPS51163 also supports output pre-biased startup. 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.
