hi friends I need a simple amplifier circuit that would amplify as low as 4ma to about 600ma-800ma to drive about 30 to 40 leds please I love very simple circuit if a single transistor is possible it will be better thanks
You can't just create power out of thin air. If your inverter supplies 5ma at 5 volts that's all you can get out of it. If you need more power than that you have to have a more capable power supply.
You need to specifically state what you're trying to accomplish here and exactly what hardware you currently have because what you're saying doesn't make sense.
