Hi,
We use LM5160A for flybuck. The input is 9~36VDC and output is 24V. And we require power as following:
- 24VDC / 0~200mA
- 12VDC / 35mA (Using 78L12 LDO)
There is a problem is that when the input of LM5160A under 12.5V, the U3(LDO) temperature is very high(>100ºC).
Do you have any recommend?
best Regards,
Aaron
P.S.The load always 35mA / 12VDC.
