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.
