At light load currents, the TPS6262x converter operates in power-save mode with pulse frequency modulation (PFM).

It prevents the converter from turning on the switch or rectifier MOSFET under undefined conditions. The TPS6262x device have a UVLO threshold set to 2.05V (typical). Fully functional operation is permitted down to 2.1V input voltage.

The internal compensation is optimized to operate with an output filter of L = 0.47μH and CO = 4.7μF.

Ceramic capacitors with low ESR values have the lowest output voltage ripple and are recommended. For best performance, the device should be operated with a minimum effective output capacitance of 1.6μF.
