Hi,
We got a question from the customer about LM3445.
Could you help us?
[Question]
How can we estimate the start-up time under the following condition?
Topology: Isolated Flybuck
Dimming: Triac dimming
Vin: AC90~110V
Vf: 30~42V
Iled: 3mA (1% of max 300mA); conduction angle is 35 degree
Their requirement of start-up time is less than 1sec. Are there any ICs to meet their requirement?
Best Regards,
