The TPS55285 integrates four MOSFETs providing a compact design for a variety of applications and is optimized for converting battery voltage, USB Power Delivery (USB PD) or adaptor voltage into power supply rails. Through the I2C interface, the output voltage can be programmed from 0.8V to 22V with 10mV step and the output current limit is programmable up to 6.35A with 50mA step, which is a good choice for USB PD applications. The TPS55285 has adjustable external loop compensation, programmable switching frequency, optional spread spectrum and rich protection features. All these features bring flexibility and design optimization for overall performance, as well as BOM optimization and design cost.
