illustrate

The TPS51113 and TPS51163 are cost-optimized, feature-rich, single-channel synchronous buck controllers that convert to as low as 1.5 V input voltage V from a single 4.5 V to 13.2 V supply

The controller implements voltage-mode control with fixed switching frequencies of 300 kHz (TPS51113) and 600 kHz (TPS51163). Overcurrent (OC) protection uses a low side_targetR_DS（ON）Current sensing with user-programmable thresholds. The threshold set by the owners corporation consists of a grounding resistor from the LDRV_OC pin. The resistor value reads the overcurrent programming circuit for the start-up sequence calibration phase LDRV_OC pins of the 10 microamp process.

The output TPS51113/TPS51163 prebias startup is also supported.
