When signal is present (after the band-pass filter) then output signal from analog comparator is used to unmute the LM3886 and switch-on the LM3886 power supply. Analog key is used to quickly discharge C2 capacitor. Normally this capacitor is used to leave the power on even after the input signal is off(for around 10 minutes). Both input signal and AC power supply cycle is simulated (using the damping factor) to show how the output signals changes through the sequence.</p> About text formats Tags LM3886PowerAuto on-offAuto MUTE Select a tag from the list or create your own.Drag to re-order taxonomy terms.

AC-DC Power Adapter Designer197889 × Member for 7 years 6 months 8 designs 1 groups Add a bio to your profile to share information about yourself with other SystemVision users. https://explore.partquest.com/node/242754 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/242754"></iframe> Title Description <p>This is a circuit design for a typical wall-plug power adapter. </p><p>The sinusoidal source represents a typical US 60 Hz, 120V AC wall supply. </p><p>A transformer steps the voltage down to a manageable range to be rectified for a 5V DC supply, but the waveform is still sinusoidal. </p><p>The 4 diode bridge rectifier takes this lower amplitude sinusoidal signal and produces a DC biased result, but still with noise resulting from the rectification process.</p><p>The capacitor before the voltage regulator chip helps smooth some of this noise. Then the regulator chip provides a self-contained, feedback controlled mechanism to keep the output voltage at the specified value. </p><p>The output capacitor further smooths any output ripple and provides a reservoir of charge to supply any surge in current load that may be encountered.</p><p>This example includes a load resistor that allows the exploration of the effects of load. The load is varied during the simulation and it can be seen that above a load of 100 mA, the regulation of the output voltage begins to deteriorate.</p><p>The addition of a few components can make it possible for such a circuit to provide significantly higher power loads. See http://www.systemvision.com/design/ac-dc-power-adapter-current-boost-regulator for an example.</p> About text formats Tags PowerVoltage RegulatorAC-DC Convertertransformerpower supply Select a tag from the list or create your own.Drag to re-order taxonomy terms.
