Home theaters are getting to be extremely popular among American homes. This modern technology is slowly giving movie theaters a run for their money. Basic knowledge of home theater system and its basic components may be best for people who want to bring home relaxation and entertainment.  The most important consideration in the design and complete set up of your home theater is the size of the room. The home theater speakers and the other components of your home theater may need to consider the size of the room. Too small rooms for your home theater may not require so many speakers. Only three speakers may be good if the room is quite small.  Do not overload your small room; you may not be able to get the entertainment and relation you want if you feel overloaded with so many home theater speakers. Because you only need three home theater speakers in your small room, you may need to acquire the high-end brand of home theater speakers to compliment the size of the room and th...

Positive output step-up and step-down dc-dc converters have a common limitation in that neither can handle input voltages that are both greater than or less than the output. For example, when converting a 12-V sealed lead/acid battery to a regulated +12 V output, the battery voltage might vary from a high of 15 V down to 10 V. By using a MAX641 to drive separate P-and N-cbannel MOSFETs, both ends of the inductor are switched to allow non inverting buck/boost operation. A second advantage of the circuit over most boostonly designs is that the output goes to 0 V when shutdown is activated. Inefficiency is a drawback because two MOSFETs and two diodes increase the losses in the charge and discharge path of the inductor. The circuit delivers +12 V at 100 mA at 70 percent efficiency with an 8-V input. Step up Down DC - DC Converter Circuit Diagram
