1.5 A in a 3x3 mm VSON — power density for tight boards
The TPS62510DRCTG4 is a 1.5 A adjustable step-down (buck) regulator from Texas Instruments, switching at 1.5 MHz to keep the inductor and output capacitors small. The 10-VSON (3x3 mm) package with exposed pad pulls heat into the PCB ground plane, making this a fit for space-constrained portable and industrial designs where board area is the constraint.
Switching frequency and inductor sizing
At 1.5 MHz the regulator can use a 2.2 µH to 4.7 µH inductor, which sits in a 0805 or 1210 footprint.
Input and output voltage range — what it covers
The adjustable output goes from 0.6 V up to the input voltage, which covers the core voltages for most low-power MCUs and wireless SoCs in the 1.2 V to 3.3 V range.
