TPS55165-Q1 is an automotive AEC-Q100 Grade 1 synchronous buck-boost regulator for fixed 5 V or 12 V rails from a varying vehicle or industrial input.

Best for

  • Automotive 5 V standby or ECU rails
  • Automotive 12 V regulated rails
  • Input supplies that cross above and below the output voltage

Avoid if

  • A fixed output above 12 V is required
  • More than the specified derated output current is required at low VIN
  • Low-power mode protections are required to remain active

Check before use

  • Maintain more than 5.3 V during startup until the output passes the PG undervoltage threshold.
  • For 12 V output, pull PG up only to an external 5 V supply.
  • Connect VREG_Q to VREG with a Kelvin connection to the VREG decoupling capacitor.
