- Selecciona el inductor con Isat ≥ 1.2× la corriente pico prevista y baja DCR; diseña el rizado en el 20–40% de la carga plena.
- Usa cerámicos de baja ESR y colócalos muy cerca de VIN/VOUT y pines de GND del IC.
- La guía SLVU806 incluye el esquema, layout y la lista completa de materiales del EVM; es el mejor punto de partida para tu PCB.
