The TPS6262x device family provides high-frequency synchronous step-down DC/DC converters
optimized for battery-powered portable applications. Intended for low-power applications, the
TPS6262x devices support up to 600 mA load current, and allow the use of low cost chip inductor and
With a wide input voltage range of 2.3 V to 5.5 V, the devices support applications
powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions
are available from 1.2 V to 2.3 V.
The TPS6262x devices operate at a regulated 6-MHz switching frequency and enter the
power-save mode operation at light load currents to maintain high efficiency over the entire load
The pulse frequency modulation (PFM) mode extends the battery life by reducing the
quiescent current to 31 µA (typical) during light load and standby operation. For noise-sensitive
applications, the device can be forced into fixed frequency pulse width modulation (PWM) mode by
pulling the MODE pin high.
The TPS6262x devices operate over a free air temperature range of –40°C to 85°C. They are
available in a 6-pin chip-scale package (WCSP).
