MOSFET Power Amplifier 5200W IRFP250

MOSFET Power Amplifier 5200W IRFP250
This is the circuit design of Mosfet power amplifier 5200W RMS, the schematic is for single channel. The circuit uses 16x IRFP250 to gain 5200W RMS power output at 2 ohms load. To feed this circuit , you will need 150 volts dual polarity (symmetrical) power supply of course with very high DC current. (more…)

260W Power Audio Amplifier

260W Power Audio Amplifier
This the circuit diagram of 260W power audio amplifier capable of delivering up to 260W RMS at 8 Ohms load. The signal level of 1 VPP standard amplitude is input to a differential stage composed of BC556C Transistor. Then the signal is input to the post-formed by complementary transistors in order to achieve the desired power. (more…)

1 Watt Stereo Audio Amplifier based IC KA2209

1 Watt Stereo Audio Amplifier based IC KA2209
Above schematic diagram is 1 Watt stereo audio amplifier based IC KA2209 can be used for small electronic device such as radio, smartphone, tablets or other gadgets which require little sound amplification :D This is the text book circuit for this IC in stereo mode. It is ideal for battery powered operation. Power output depends critically on speaker resistance & supply voltage. At 3V into 4 ohm speakers the power is 0.1W. At 6V into 4 ohm speakers it

1000W Power Audio Amplifier

200W Mono / Stereo Power Amplifier using TDA1514A

200W Mono / Stereo Power Amplifier using TDA1514A
This is circuit design of 200W mono / stereo power amplifier using TDA1514A. This circuit support mono and stereo channel. Mono channel uses bridge configuration, so the mono choice will be give power output by twice than stereo choice. A symetrical power supply (dual polarity) is required to powered this circuit. Power supply voltage (+) 28VDC and (-) 28VDC max. (more…)
