TPS55288 buck-boost converter EVM with 400kHz operation frequency


Order now


The TPS55288 is a synchronous buck-boost converter optimized for converting battery voltage or adaptor voltage into power supply rails.

The TPS55288 integrates two 16-A MOSFETs of the boost leg to balance the solution size and efficiency for USB Power Delivery (USB PD) application.

The TPS55288 has up to 36-V input voltage capability. It can output 15 A when working in buck mode. When working in boost mode, the device delivers 100 W from 8-V input or 60 W from 5-V input.

  • Input voltage range: 2.7 V to 36 V
  • Output voltage range: 0.8 V to 21.26 V
  • 97% efficiency at VIN = 12 V, VOUT = 20 V and IOUT = 3 A
  • Adjustable switching frequency 200 kHz to 2.4 MHz
  • Programmable output current limit
  • I²C Interface
