500 mA point-of-load buck — input range and output adjustability
The TPS62300DRCR: Switching at 3 MHz keeps the inductor and output capacitor small — a 1 µH inductor and 10 µF ceramic typically fit the loop, saving board area in space-constrained portable or module designs.
Synchronous rectifier and temperature grade
The integrated synchronous rectifier eliminates the external Schottky diode and improves efficiency at light loads — the part maintains >80 % efficiency down to about 10 mA load, which matters for battery-powered or always-on subsystems.
The 3x3 mm footprint and 0.5 mm pitch make it routable on a two-layer board if the ground plane under the pad is continuous; a four-layer stack-up with a dedicated ground plane improves thermal spreading and reduces switching-loop inductance.
