Product details

1.2 A synchronous buck in a 3×3 mm footprint

The TPS62043DGQR: The 1.25 MHz switching frequency allows the use of a small inductor and a ceramic output capacitor.

Input range and output voltage — what fits

Input minimum is 2.5 V, so a single Li-ion cell (3.0 V–4.2 V) or a 3.3 V rail works without a boost pre-regulator. The 6 V maximum covers 5 V ±10 % rails cleanly. The output is fixed at 1.6 V — no external divider resistors, no feedback loop compensation to tune. That fixed output is a BOM simplification, but it also means the part is locked to that voltage; if your load needs 1.8 V or 1.2 V, this is not the variant.

Frequently asked questions

What package does TPS62043DGQR come in?

It is supplied in a 10-PowerTFSOP / 10-MSOP (0.118", 3.00 mm width) package, also designated as 10-HVSSOP. The device has an exposed thermal pad.
