The Metamere Series offers a 50W power module in the
industry’s standard surface-mount footprint. The
Metamere series utilizes a low component count that
results in a low cost while still providing high performance.
The open-frame, compact design provides flexibility by
performing local voltage conversion of either a 5V or 3.3V
bus. The low weight, surface mount design is well suited
for almost any manufacturing environment.
