TPS55289QWRYQRQ1 is an automotive AEC-Q100 Grade 1, I2C-programmable synchronous buck-boost converter for 3 V to 36 V inputs and outputs up to 22 V.

Best for

  • Automotive programmable power rails
  • USB PD programmable power supply designs
  • Applications requiring buck and boost operation from one regulator

Avoid if

  • Applications requiring output voltage above 22 V
  • Designs without capability to validate external compensation and thermal performance
  • Systems requiring a fixed non-I2C-controlled converter architecture

Check before use

  • Validate worst-case input-to-output power conversion and inductor saturation current
  • Set I2C output-voltage, current-limit, and operating-mode registers before enabling output
  • Verify OVP margin when programming output near 22 V
  • Follow the recommended PGND, AGND, switch-node, bootstrap, and current-sense layout guidance
