Texas Instruments TPS55289 8A Buck-Boost Converter

Texas Instruments TPS55289 8A Buck-Boost Converter
Texas Instruments TPS55289 8A Buck-Boost Converter is a synchronous buck-boost converter optimized for converting an adapter or battery voltage to a power rail voltage. The TPS55289 integrates four MOSFET switches to provide a compact solution for USB powered applications. The TPS55289 has an input voltage capability up to 30V. The output voltage is programmable through the I2C interface from 0.8V to 22V in steps of 10mV. The device can deliver 60W from a 12V input voltage when operating in boost mode. It is capable of delivering 45W at a 9V input voltage.
