Description
AI
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.
