3W Stereo Amplifier schematic
3 Watt stereo amplifier circuitusing MAX 7910 IC. The MAX9710 a stereo audio power amplifier IC capable of delivering 3Watts of out put to 4 Ohm loads. MAX9710 can be operated from a single 4.5V to 5.5V power supply , makes it ideal for hand held applications.The IC for 3 Watt stereo amplifier circuit also features thermal overload protection.
Circuit Schematics 3 Watt Stereo Amplifier MAX 7910
| 3 Watt stereo amplifier circuit |
This 3 Watt stereo amplifier circuit is suitable for small power audio devices such as radio sets and portable CD players. 5 V DC power supply is used for powering the 3 Watt stereo amplifier circuit. 6V battery with an IN 4007 diode series to the positive terminal of it can also be used instead of 5 V DC supply. The 3 Watt stereo amplifier circuit will get a supply voltage approximately 5 V after 0.7 V voltage drop across diode.

6V 3W Bicycle Generator System Circuit
6V/3W Bicycle Generator System Circuit
This is a regulator for a 6V/3W bicycle generator system. The purpose is to switch to rechargeable batteries when the generator is idle. In addition, the device limits the voltage across the bulbs when the generator operates at a high speed. As you can see, the schema is purely electrical. In the presented design, the switch has been moved, compared to the original to a location where the switch better functions under different circumstances. I kept the regulator on the bike for 2 years during which the schema operated fairly satisfactorily. Thereafter, I moved on to an electronic regulator optimized for the operation with a hub dynamo.
