Tool/software: WEBENCH® Design Tools
Dear TI guide,
I have a question for AC/DC SMPS.
I need to design a SMPS circuit board respond below requestion.
- Input: AC (85V~235V)
- Output: DC (12V, 5A)
- Output Efficiency: Follow CoC Tier 2 (No load: <= 0.15W, 10% Efficiency Load: >=79%, Full load: >=89%
I tried to use WEBENCH to reference design, but all refer circuit have efficiency result: under 90% (full load), under 79% (10% Eff. Load).
So can you guide me a IC or Circuit to respond above requestion?
Hope to receive your help.
Thanks!
