Ebay will probably be your cheapest bet. I've been checking around there lately since I am also looking for one. Occasionally they have bulk lots for sale, but the parts are either scrap or just barely hanging on. Llama.com also sells them, but I figured if i was to buy from them, I would be better off buying a new controller from ebay that comes with the shell and parts since it would be around the same price. Hope you find a better answer;) pass the news too if you do
Fuse is a device that acts as a traffic controller in the electric circuit, it means it breaks the circuit when the power of current is more than what it it needed and prevents the possible damages ...
IC means integrated circuit the name controller refers to its function control.

May be the Voltage controller circuit. Control the voltage for charging, and cut off when full charged.
An inrush current preventing circuit includes a rectification circuit, a temperature-sensitive component, a controller, a switching circuit, and a tank circuit. The controller outputs a control signal to turn on the switching circuit in response to the tank circuit being at a substantially full voltage, and the rectification circuit and the switching circuit forming a current loop for providing power from the rectification circuit to an electronic device. The controller outputs no control signal to turn off the switching circuit in response to the tank circuit being undercharged, and the rectification circuit and temperature-sensitive component forming a current loop for providing power from the rectification circuit to the electronic device for protecting the electronic device. the rectification circuit and the switching circuit forming a current loop to provide power from the rectification circuit to the electronic device;wherein the controller does not output a control signal to turn off the switching circuit in response to the tank circuit being undercharged, the rectification circuit and temperature-sensitive component forming a current loop to provide power from the rectification circuit to the electronic device such that an excess amount of current is prevented from flowing to the electronic device
Not good.
