Part Number:TPS23751
Dear all
The efficiency of my board is 80% when output is 12V@2.1A, and when output is 12V @1A.
I have some questions about this:
1. In the datasheet, "Figure 29. TPS23751 and TPS23752 Light Load Efficiency versus Mode", there has up to 85% efficiency at 0.9A, Could you show me the curve of efficiency at output from 1A to 2A ?
2. What factors affect efficiency ? Could you show me how to improve conversion efficiency ?
