Voltage Regulators - DC DC Switching Regulators

synchronous buck15 A4.5 V to 14 V inputPQFN PowerPADprogrammable current limit

TPS56121DQPT is a 15 A integrated synchronous buck regulator for converting 4.5 V to 14 V rails to outputs regulated from a 600 mV reference.

Best for

  • High-current point-of-load rails
  • Telecom and networking DC-DC rails
  • Compact 15 A synchronous buck designs

Avoid if

  • Input voltage exceeds 14 V
  • A lead-free RoHS-compliant device is mandatory without confirming the exemption

Check before use

  • Confirm thermal margin at maximum load
  • Set and validate the low-side overcurrent threshold
  • Keep the SW node compact and feedback routing away from SW and BOOT traces
