Voltage Regulators - DC DC Switching Regulators

automotivebuck regulatorsynchronous3 A2.1 MHzHTSSOP PowerPADwide input

LM53603AQPWPRQ1 is a 3 A automotive synchronous buck-regulator variant in TI's 16-pin HTSSOP PowerPAD family, designed for wide-input DC/DC conversion.

Best for

  • Automotive 12 V or wide-input point-of-load rails
  • 3 A synchronous step-down conversion
  • ADAS, infotainment, instrument-cluster, navigation, and HUD power

Avoid if

  • The required output-voltage option has not been confirmed from the full ordering information
  • The application cannot accommodate a switching regulator with a 2.1 MHz nominal frequency

Check before use

  • Confirm exact output-voltage and feedback configuration
  • Check dropout margin at minimum input voltage and full load
  • Validate junction temperature with the actual PCB copper area and thermal vias
  • Do not leave EN, FPWM, or SYNC floating
