Author C. Johnson C. Johnson A 20090310 Renumbered & released. C. Johnson A01 20091012 Re-drew with updated symbols. C. Johnson A1 20120216 Replaced Micrel port power with Maxim programmable 1-4A J. Hancock controller. Added ILIM Resistor to set this new part to 2A. A2 20130731 20150901 DNP'd 1.0uF FILT caps and populated 0.1uF FILT caps. J. Hancock Replaced PPC on Port 1 with Micrel part. Removed trim resistor tied to old MAX part. J.
