After finding a download of the circuit diagram for his CSI3003X-5 supply he was able to ... which is normally used to set the power supplies’ constant current limit anyway.

Through simple circuit modifications, designers can use peak current limiting to produce a constant current source. Fault protection is a critical function of all power supply controllers.

The V+ supply voltage (18 V ... R LIMIT1 and R LIMIT2 limit the load current to approximately 120 mA. This circuit maintains a fairly constant load power over a 50:1 variation in load and for ...

A conventional power ... supply. The conventional supply cannot, however, operate in either the second quadrant as an adjustable load for a minus supply, for example, or the fourth quadrant as a ...

Although this sample rate would provide inadequate control response for most power supply applications, it works well for LED applications because the LED presents a constant ... the buck circuit and ...

How easy is that? An LED tester can be as easy as a constant-current power supply, and in fact that’s what [Dave]’s first LED tester was, in essence. Set an LM317 circuit up to output 10mA ...
