Voltage Regulators - DC DC Switching Regulators

buck regulator42 V input2.5 Anon-synchronousMSOP-PowerPADEco-Mode

TPS54240DGQ is a 42 V-input, 2.5 A non-synchronous buck regulator in a 10-pin MSOP-PowerPAD package, intended for compact industrial and communications supply rails.

Best for

  • 12 V and 24 V industrial input rails
  • Compact non-isolated buck supplies
  • GSM/GPRS and low-power communications loads

Avoid if

  • A synchronous regulator is required to reduce catch-diode loss
  • Input voltage can exceed the 42 V recommended operating limit
  • A fully integrated power stage without external diode is required

Check before use

  • Select a catch diode with reverse-voltage rating at least equal to maximum input voltage.
  • Connect a 0.1 µF ceramic bootstrap capacitor between BOOT and PH.
  • Solder the exposed PowerPAD to PCB ground copper with thermal vias.
  • Verify current-limit margin because the specified threshold has wide variation.
