The input range maps directly to a single-cell Li-ion battery (3.0 V to 4.2 V), two alkaline cells in series, or a 3.3 V regulated rail. The 1.5 A continuous output current is sized for powering a small SoC, FPGA core, or a cluster of sensors — not a main processor rail, but a local post-regulation stage.
1.5 MHz switching shrinks the passives
The 1.5 MHz switching frequency lets the designer use a 2.2 µH to 4.7 µH inductor and 10 µF output capacitor — small 0805 or 0603 footprint parts.
10-VSON (3x3) — thermal via pattern required
The datasheet recommends a 2x2 array of 0.3 mm thermal vias under the pad to the ground plane — without them the junction-to-board thermal resistance rises above the 40°C/W typical figure.
The base product number TPS62510 spans several output-current and package variants; the DRCR suffix identifies the 10-VSON reeled option.
