Other Parts Discussed in Thread: UCC28730
Hi,
I checked the efficiency on WEBENCH using the UCC28630 flyback power supply.
The normal load is 10A, and the efficiency at this time exceeds 80%.
However, when the load is 0.3W (5V x 0.06A), it is as low as 28%.
I need to achieve more than 80% efficiency with this circuit at VIN = 240V, VOUT = 5V, POUT = 0.3W.
What are some ways to increase efficiency?
