Hi,
We are designing a 100 Watt Push-Pull converter using LM5030. The input to the system is a 12Volt DC supply.
1.Recommended operating range of VCC and the ability to float VIN pin
Is it possible to connect 12V directly to the VCC pin of LM5030? At the same time by making the VIN pin of LM5030 to float.
2.Supply current limit of VCC and Power dissipation of LM5030
The maximum current limit for the VCC of LM5030 is listed as typically 17mA.
If VCC is powered with 12V then the power dissipation of LM5030 is given by (12-7.7)*0.017 = 73mWatt.
Does the above calculation is correct?
Thanks and regards
