Introduction
The TPS6261x, TPS6262x, and TPS6266x devices are series of high-frequency, synchronous, step-down
dc-dc converters optimized for battery-powered portable applications. Intended for low-power applications,
the TPS6261x, TPS6262x, and TPS6266x support up to 350-mA load current, and allow the use of
low-cost chip inductors and capacitors. With a wide input voltage range of 2.3 V to 5.5 V, the devices
support applications powered by lithium-ion (Li-Ion) batteries with extended voltage ranges. Different fixed
voltage output versions of the TPS6261x, TPS6262x, and TPS6266x are available from 1.2 V to 2.3 V.
These converters operate at a regulated 6-MHz switching frequency and enter a power-save mode
operation under light load currents in order to maintain high efficiency over the entire load current range. A
PFM mode extends the battery life by reducing the quiescent current to 31 µA (typ) during light load
operation.
