FAE Expert Insights
"The XZ3003 is the smallest power module in our lineup, and it's perfect for wearables where space is absolutely critical. The 2.5mm x 2.5mm package is incredibly small - you can fit this almost anywhere. I've used this in smartwatch designs where PCB area is measured in square millimeters. The 1A capacity is sufficient for most wearable processors and sensors. The automatic power-save mode is essential for battery life - it keeps efficiency high even when the device is sleeping. The 3MHz switching allows use of tiny 0402 inductors inside the module. Trade-offs are slightly lower efficiency and thermal capability compared to larger modules, but for wearables, the size savings are worth it."
