Description
General part information
TPS55289 Series
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.
The TPS55289 has up to 30-V input voltage capability. Through the I2C interface, the output voltage of the TPS55289 can be programmed from 0.8 V to 22 V with 10-mV step. When working in boost mode, the device can deliver 60 W from 12-V input voltage. It is capable of delivering 45 W from 9-V input voltage.
The TPS55289 employs an average current-mode control scheme. The switching frequency is programmable from 200 kHz to 2.2 MHz by an external resistor and can be synchronized to an external clock. The TPS55289 also provides optional spread spectrum to minimize peak EMI.
