TPS6125xA 4A Boost Converter

Texas Instruments TPS6125xA 4A Boost Converter provides a power supply solution for battery-powered portable applications. With the input voltage ranging from 2.3V to 5.5V, the device supports the applications powered by the Li-Ion batteries with an extended voltage range. Different fixed output voltage versions of 4.5V, 4.7V, 5V, and 5.2V are available. The TPS6125xA supports up to 1500mA load current from a battery discharged as low as 3V. The TPS6125xA operates at a typical 3.8MHz switching frequency. The Texas Instruments TPS6125xA could be flexibly configured in Auto PFM, forced PWM, or ultrasonic mode. The Auto PFM mode could benefit from 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 25kHz at any load condition to avoid acoustic noise.
