Product details

Dual-output synchronous buck controller for 5V/12V/24V rails

The TPS53124RGET is a dual-output synchronous buck controller from TI's D-CAP™ series, built for point-of-load regulation from 4.5V to 24V input rails. Two independent transistor-driver outputs, each with enable control, let it power separate core and I/O voltages from a single supply. The synchronous rectifier keeps efficiency high at low output voltages — a real advantage when you're dropping 12V to 1.8V or 3.3V.

Input supply range spans 4.5V to 24V, covering standard 5V and 12V rails plus 24V industrial buses. That means it fits factory-floor gear, outdoor telecom cabinets, and indoor power supplies, but not engine-bay or downhole tools.

Package and footprint — 24-VQFN with exposed pad

Housed in a 24-VQFN (4x4 mm) with exposed thermal pad. Cut Tape or Tape & Reel — reel preferred for volume, Cut Tape for prototypes.

Frequently asked questions

Is TPS53124RGET lead-free?

ROHS3 compliant — no lead, no restricted phthalates. No exemption needed for EU markets.

Is TPS53124RGET suitable for point-of-load regulation?

Yes — dual outputs, synchronous rectifier, and a 4.5V–24V input range make it a natural fit for POL converters that need separate core and I/O voltages from a single bus.
