The gate driver voltage is 10V.You simulation circuit doesn't show the actual gate driver voltage.
How to do that?It should be applied between gate and source, not between gate and ground.
Thank you for your fast response.10 V gate voltage referred to ground is too low, it doesn't turn the MOSFET completely on. Required is 30 to 35V referred to ground, but there's a risk to exceed the maximum Vgs rating.
Hi,
Did you read post#2?
About "duty cycle" .... and "regulation"
Klaus
So why your question in post#7 ... when it is already answered?
So, did you modify the duty cycle, or did you add a regulation loop...Because that answer doesn't solve my probleme.
Hi
So, did you modify the duty cycle, or did you add a regulation loop...
If YES: You did not give any information about this. Please show the modifed circuit.
If NO: how can you expect a modifed output voltage?
Klaus
Hi,
At 10k and 5V, load current is 5V/10k=500uA.
Is that your design spec?
.
No, I want at least 20mA to turn a LED on.
It is a white LED so the Vf must be between 3.3V and 5V.So what's the forward voltage of the LED?
