Texas Instruments TPS61253A 4A Boost Converter, Now at Mouser, Offers Power Flexibility for Battery-Powered Applications



Mouser Electronics, Inc., the authorized global distributor with the newest semiconductors and electronic components, is now stocking the TPS61253A 4A boost converter from Texas Instruments (TI). The TPS61253A delivers a variety of features that enable the device to drive a multitude of portable power management applications, such as smartphones and USB charging ports, requiring fewer external components than other solutions.

The TI TPS61253A 4A boost converter, available from Mouser Electronics, features an input voltage range from 2.3 V to 5.5 V with a fixed output voltage of 5.0 V and supports applications powered by Li-Ion batteries with a load current up to 1500 mA. Integrated with a 35-milliohm low-side FET and 60-milliohm high-side FET, the TPS61253A operates at a quasi-constant 3.8-MHz frequency in pulse width modulation (PWM) mode, and manages power load currents ranging from moderate to heavy. During PWM operation, the converter uses a quasi-constant, on-time, valley current-mode-control topology to achieve excellent line and load regulation.

For flexibility in power load conditions, the TPS61253A device offers designers three selectable modes: Auto PFM, Forced PWM, and Ultrasonic. The Auto PFM mode enables high efficiency at a light load, whereas the forced PWM operation can make the switching frequency constant across the whole load range. To avoid acoustic noise, the ultrasonic mode keeps the switching frequency always higher than 25 kHz at any load condition. Other features of the device include a built-in 600-μs soft start time, a thermal shutdown and a hiccup mode that enables automatic recovery after output shortages.
