If you have a current-sense circuit, then you don't need a constant-current circuit, you just need a voltage regulator, such as an LM317, whose voltage is controlled by the P;WM signal. You then control the current by adjusting its output voltage. Below ...
Integrated circuits such as the LM 317 and 723 enable us to fine-tune the output voltage to a precise constant value. The figure below shows the LM317voltage regulator. The output voltage can be adjusted by adjusting the values ofresistancesR1and R2. Usually, couplingcapacitorsof values about ...

The LM317 is just like any otherlinear regulatorwith an input and an output pin, but instead of a ground pin there’s a pin called ‘adjust’. This pin is designed to get feedback off of a voltage divider across the output so that the pin is always at 1.25V, by varying the resista...
Fast Recovery Diodes Semiconductor Devices Electronic Component Zk2000A/3600V We supply various shapes of fast recovery diodes that have a small reverse recovery time. Its maximum voltage is 4500V, the maximum current is 3000A. Our rectifier diode has a fast rec...
Re: What is a good hobbyist's starter kit? « Reply #1 on: November 13, 2016, 12:56:57 pm » * Get two multimeters, even if the other one is a cheapie. Being able to measure two things (voltage/current, or input/output of an LDO) is very useful.* If your friend is comi...

A sensor is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage and display...
The output voltage, also known as the Hall voltage, (VH) of this fundamental Hall Element is directly proportional to the strength of the magnetic field passing through the semiconductor material (output ∝ H). This output signal voltage can be very small, just a few microvolts even if expos...
In most cases a mains transformer-bridge rectifier- reservoir capacitor raw supply is adequate for the input to a three terminal regulator, like the LM317 or LT1086. And providing that you use the components specified in the datasheet, you will have a stabilized supply line more than adequate...
