Dear Sir/Madam,
We are using a LM5160 for converting a 5.24 V to a higher isolated voltage of 23.4 V.
Vin: 5.00 V to 5.50 V with V nominal 5.24 V.
Output is 23.4 V with 30 mA capability (700 mW load only).
The transformer has a ratio of about 10.
When varying the input voltage from 5.0V to 5.5 V we have about 5 V of Vout_isolated.
What can be done to reduce the dependency with the input voltage variation, please?
We use a modified Evaluation Board (LM5160) with a custom transformer of 30 uH primary and 350 KHz switching.
We look forward to hearing from you soon.
Yours faithfully,
Francois Arnaud
