I want to build a PWM circuit for a led flashlight mod based on IC555. I can only find 200mah max output, but I want to drive LED at 400mah. Am I missing something? How do I go about this? Thanks.

A 555 is rated for a max of 200ma, you're gonna have to use a transistor.

Do you need some help doing this?

Show us how you would do it if you had such a 555. It'll give us a starting point.
