What is your project? You haven't eluded to what you want to do yet.
Basically I just need more "stock Arudino" PWM pins. Edit - to clarify what I posted above, the LEDs are HP LEDs and I can't drive them directly from a chip like that. I have drivers; I just need to control the drivers with a PWM signal.
Accurate linear dimming is compatible with PWM frequencies from 100 Hz to 5 kHz for PWM duty cycle down to 1%. PWM frequencies up to 50 kHz can be supported for duty cycles greater than 10%.
At this point I really wouldn't mind a weird package, but the frequency looks too high on that chip. Here's an excerpt from the datasheet of the IC I'm using for LED driving:
But why would you need a LED Driver? the IC I referred to is specifically for that.
There were some discussions a while back on a software PWM solution that does PWM on any digital pin
It's not the cleanest way, but you can drive each LED output into a resistor load and pull a signal off the + side for your drivers. Configure the output so that you're getting the voltage you want at as low of a current as possible. For example, set the output current to 10.6mA and run it through a 470 ohm resistor to get a 5V output.
The only problem with this chip is that it's in a TSSOP package, wish I could get it in dip or at least ssop.
