Voltage Regulators - DC DC Switching Regulators

dual bucksynchronous regulator5 Acurrent sharingHTSSOP PowerPAD

TPS65279DAPR is a dual 5 A synchronous buck regulator for 4.5 V to 18 V rails. Its channels can operate separately or be paralleled in current-sharing mode for up to 10 A.

Best for

  • Dual point-of-load rails up to 5 A each
  • Two-phase current-sharing rails up to 10 A
  • Intermediate-bus power conversion

Avoid if

  • Input voltage exceeds 18 V
  • The design cannot provide adequate thermal copper and exposed-pad soldering
  • A single output above 10 A is required

Check before use

  • Verify package thermal dissipation at maximum load
  • Select compensation for the actual output filter
  • Use the documented current-sharing pin configuration when paralleling channels
