So I made the DC-DC converter for my LED, and it doesn't seem to be working right.
If I turn the variable resistor one way, it gets dimmer, and I can see oscillations all over the circuit with my o-scope, but it is very dim, and the voltage feeding the LED is not any more than the supply voltage. If I turn the POT the other way, the circuit stops working, and the LED gets brighter because its just being direct-driven through the inductor.
The LED current is a measly 20 mA because the battery voltage is a little under 3 volts. i cant wait to see this thing @ 350mA!
Anyone have a clue whats going on??
