Can an Atmega328 +oscillator run off of 3.7 volts without a regulator to be used for 7 channel pulse width modulation with mosfets to drive the leds? I'm desiring to power it with an 18650 battery. (which charges to 4.2 volts and drains to 2.75 volts) http://www.dealextreme.com/details.dx/sku.5790 …

Atmega328 powered by a 3.7 volt battery?

A 3.3V/8MHz Promini running on a 3.7V LiPo battery will control those LEDs just fine for you.
