Product Brief: Metamere iAA Series – Non-isolated Surface Mount Power Module  
Metamere iAA Series DC/DC Power Modules  
3 and 5V Inputs, 15A Output  
Surface Mount Power Module  
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.
