Product details

1.2 A synchronous buck in a 10-pin HVSSOP

The 1.25 MHz switching frequency keeps the inductor small — typically 4.7 µH to 10 µH — which matters when board area is tight and the load is a 1.8 V rail for an MCU, FPGA core, or RF front-end.

Fixed 1.8 V output — one less divider

The output is factory-set to 1.8 V, so no external feedback resistor network is needed. That saves two components and one feedback-node routing headache. The synchronous rectifier improves efficiency at light loads, which is relevant for battery-powered or always-on systems where quiescent current matters.

Frequently asked questions

What is the difference between TPS62044DGQRG4 and TPS62044DGQR?

The suffix 'G4' on the TPS62044DGQRG4 indicates a lead-free (RoHS-compliant) finish variant. The TPS62044DGQR is the earlier tin/lead version. Both are functionally identical — same 1.2 A output, same 1.25 MHz switching, same fixed 1.8 V output. The G4 variant is the preferred choice for RoHS-compliant assemblies.
