IC LM4651 and LM4652 is a type of MOSFET ICs and power amplifiers include high-efficiency amplifier, suitable for self-powered speakers, a subwoofer and driver quality car. LM 4651 is a fully integrated conventional pulse width modulation (PWM) driver, contains undervoltage, short circuit, overmodulation. The maximum efficiency of this circuit is 85% at 125W in standby […]

Variable PC power supply Circuits
Variable PC Power Supply Circuits variable variable Power Supply Circuits Many alternatives abound where a HeNe laser power supply must be constructed from scratch. Decisions must be made based on the size or range of sizes of the HeNe tube(s) to be powered, convenience, need for portability (well in a relative sort of way), availability […]

DC power converter
DC power converter 12V DC to 120V DC The most obvious approach would be to make a DC power converter 12V DC to 120V DC, output at 50 or 60 Hz, but this requires a rather large and heavy transformer. So it’s better to use a high frequency, at least 25kHz, so a very small […]
