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.","metaTitle":"TPS62043DGQR Step-Down Converter, 1.2 A, 1.25 MHz, 10-HVSSOP","metaDescription":"Texas Instruments TPS62043DGQR synchronous buck converter: 2.5 V–6 V input, fixed 1.6 V output, 1.2 A, 1.25 MHz switching, -40°C to 85°C.
