Zilog - Low-Cost Fan Control Solution

Fan controllers are expensive to manufacture due to the use of expensive
components such as transformers and regulator circuitry. Find a way to reduce
the cost of building a fan control solution.

Design a Z8 Encore! XP® 8-pin Z8F04 microcontroller-based fan controller
powered by a low-cost power supply that eliminates the need for transformer and
regulator circuitry.

A simple 3.3 V low-current power supply that radically reduces component count
and manufacturing costs.
