TPS55289 - 8-A Buck-Boost Converter

General Description

The TPS55289 is a synchronous buck-boost converter that is optimized for converting battery voltage or adapter voltage into power supply rails.

The TPS55289 integrates four MOSFET switches, providing a compact solution for USB power delivery (USB PD) application.

Key Features

  • The TPS55289 has up to 30-V input voltage capability. Through the I2C interface, the output.
  • Programmable power supply (PPS) support for voltage of the TPS55289 can be programmed from USB power delivery (USB PD) 0.8 V to 22 V with 10-mV step. When working in boost.
  • 3.0-V to 30-V wide input voltage range.
  • 0.8-V to 22-V with 10-mV step programmable output voltage range mode, the device can deliver 60 W from 12-V input voltage. It is capable of delivering 45 W from.
