It needs to be adjustable over a wide range with clean square wave output Thanks I need a PWM to run 4 seperate boards of between 16 and 20 Superflux LED’s on each

Makinano Jr. Fri, 25 Sep 2009 05:16:16 +0000 http://ledcar.com/wp/?p=136#comment-65 I would like to see a PWM with good stable wide frequency range (10 Hz to 100 kHz) The square wave output must have fast rise and fall times and output flat in that range. It must be stable at varying temperatures. It must have a variable duty cycle and variable current limiting. Can this be done with minimal parts count.
