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.

TPS61253AEVM-803 — TPS61253A용 부스트 컨버터 평가 모듈

2.3V~5.5V의 넓은 입력 전압 범위를 지원하는 TPS6125xA는 전압 범위가 확장된 리튬 이온 배터리로 구동되는 애플리케이션을 지원합니다. 이 장치는 조정된 3.5MHz 스위칭 주파수에서 작동합니다. TPS6125xA는 강제 PWM 모드 또는 PFM 모드에서 유연하게 구성할 수 있습니다. PFM 모드는 낮은 부하에서 높은 효율로 배터리 수명을 연장하는 반면, 강제 PWM 모드는 잡음에 민감한 애플리케이션에 적합합니다. TPS6125xA는 또한 경부하 조건에서 낮은 음향 잡음을 가능하게 하는 초음파 모드 옵션을 제공합니다. (...)
