AN6610 Motor Speed Controller.

I been collecting some NOS stock of good old Linear ICs and found a couple of AN6610 ICs. It's been pretty hard to locate a data sheet (In English) however managed to construct a simple motor speed controller within 5 minutes of effort (on a breadboard)

The IC,

AN6610

AN6610 comes in TO-126 Package and pretty easy to use.

The data sheet I found from here


As per the data sheet, the schematic would be,

The quick and dirty construction worked well, except there is a start-stop-start pattern observed at low speeds.


Rs, I have used a 5K POT and worked fine.

Here are some pics I have taken while playing around and quick and dirty construction of the above circuit.

Components:

Unfortunately I couldn't find 470 Ohm resistor and the 22uH Inductor. I used 330 Ohm resistor instead. However it is good to do experiments by changing the value of this.
