3 A buck regulator with wide input range
The TPS5430DDA: It switches at 500 kHz, which keeps the inductor physically small while still delivering clean output ripple for most point-of-load rails. The output is adjustable from a 1.221 V reference up to 32.04 V. The single positive output is non-synchronous, so the external Schottky diode selection matters for efficiency at higher duty cycles.
Industrial temperature range and thermal footprint
Surface-mount assembly with the PowerPad needs a solder paste stencil aperture covering at least 50% of the pad area to avoid voids. The tube shipping medium (Tube) is typical for prototype and low-volume builds; reel options exist under the base number TPS5430.
