| Posted: 08 Feb 2011 04:32 AM PST Description. A simple DC to DC step up converter using LM2700 is shown here. LM2700 is a step up switching converter that has a 3.6A, 80 M ohm internal switch. It can be operated at 600 kHz or 1.25MHz switching frequency. In the circuit LM2700 is wired in order to produce 8V DC output from [...] |
| Posted: 08 Feb 2011 02:42 AM PST Description. The circuit shown here is of a 10W MOSFET amplifier that requires only a single supply. Single rail supply is seldom used in Class-B power amplifiers. Anyway, for low power applications like this it's quite fine. Actually I got this circuit from an old cassette player that is still working and I am publishing [...] |
| Car stereo amplifier using TDA2003 Posted: 07 Feb 2011 10:30 PM PST Description. A simple low power car stereo amplifier circuit based on TDA 2003 is shown here. The circuit uses cheap, readily available components and it is very easy to construct. TDA2003 is an integrated car radio amplifier from ST Micro electronics that has a lot of good features like short circuit protection for all pins, [...] |
