3.2 A buck in a 3x3 mm QFN — what that means for a point-of-load rail
The TPS62134CRGTT is a Texas Instruments DCS-Control™ synchronous step-down regulator delivering 3.2 A continuous output from a 3 V to 17 V input rail, all inside a 3x3 mm QFN package. With a programmable output from 0 V up to 1.05 V, this part is aimed at low-voltage core rails for FPGAs, ASICs, or MCUs where the load current is in the 3 A range and board area is tight. The 1 MHz fixed switching frequency keeps the inductor small while staying below the AM band for conducted EMI.
Temperature range and synchronous rectification — industrial-fit checklist
The integrated synchronous rectifier removes the need for an external catch diode, saving one component and one placement step per rail — a tangible BOM simplification for multi-rail boards. Output is positive and programmable, so a single resistor divider sets the core voltage — no factory-programmed trim or external reference needed.
Active production — sourcing posture for this TI regulator
The base product number TPS62134 covers the family; confirm the suffix 'CRGTT' for the exact programmable-output variant.
