Introduction
The TPS82671, TPS82672, TPS82675, TPS82690 and TPS82695 devices are series of high-frequency,
synchronous, step-down dc-dc converters optimized for battery-powered portable applications. Intended
for low-power applications, the TPS8267x support up to 600-mA load current and the TPS8269 support up
to 500-mA and all allow the use of low-cost chip inductors and capacitors. With a wide input voltage range
of 2.3 V to 4.8 V, the devices support applications powered by lithium-ion (Li-Ion) batteries with extended
voltage ranges. Different fixed voltage output versions of the TPS826xx are available. These converters
operate at a regulated 5.5-MHz (TPS8267x) and 4-MHz (TPS8269x) 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 17
µA (typ)
during light load operation.
