AMC6821 E2E Question
... I had a couple questions about the AMC6821. I was wondering if the IC can still provide PWM to the fan by referencing only the internal temperature sensor, or does the IC have to have the external diode temperature sensor to make a reference to. Also, I wanted to double check that the IC can still r ...

An introduction to AC/DC power supply as a simple system
... Most regulators are ICs . These are feedback control circuits that actually monitor the output voltage to detect variations. If the output varies, for whatever reason, the regulator circuit automatically adjusts the output back to the set value. Regulators hold the output to the desired value. Since ...

P–n diode
This article provides a more detailed explanation of p–n diode behavior than that found in the articles p–n junction or diode.A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p-type semiconducting layer to an n-type semiconducting layer. Semiconductor diodes have multiple uses including rectification of alternating current to direct current, detection of radio signals, emitting light and detecting light.
