Hello,
I'm building a flyback using LTC3805-5 and my input voltage conditions are 30V - 300V and have 3 outputs 18, 12 and 5.5V. The total load on my power supply is about 16W.
I wanted to know the what would be the implications of having a duty cycle less than 6% as my initial tests have suggested that the duty cycle could be as low as 1.5%. I've simulated by circuit in LTSpice & already seeing that some Gate Drive signals are being skipped/Blanks - will this be a concern?
Lpri - 56uH
Lsec - 27.7uH
Laux - 13uH
Lter - 2.7uH
Thanks,
