3 Description
The TPS61253x device provides a power supply
solution for battery-powered portable applications.
With the input voltage ranging from 2.3 V to 5.5
V (TPS61253A) or 2.5 V to 5.5 V (TPS61253E),
the device supports the applications powered by
the Li-Ion batteries with the extended voltage range.
Different fixed output voltage versions are available of
4.5 V, 4.7 V, 5 V, 5.2V and 5.25 V. The TPS61253x
supports up to 1500-mA load current from a battery
discharged as low as 3 V.
The TPS61253x operates at typical 3.8-MHz
switching frequency. The TPS61253x can be flexibly
configured at the Auto PFM mode, forced PWM
mode, or ultrasonic mode. The Auto PFM mode
can benefit with the high efficiency at the light load.
The forced PWM operation can make the switching
frequency be constant crossing the whole load range.
The ultrasonic mode keeps the switching frequency
always larger than 25 kHz at any load condition to
avoid the acoustic noise.
TPS61253x has a built-in 600-μs soft start to avoid
the inrush current at start-up. When the output is
shorted, the device enters into the hiccup mode and
recovers automatically after the short releases. During
the shutdown, the load is completely disconnected
from the input end with maximum 1.3-μA current
being consumed.
