A constant current is better than a constant voltage for driving LEDs. In this proposed circuit, a common constant-voltage regulator is changed into a constant-current source for LEDs. In addition, a ...

Podcast Technologies Power Constant Current Regulators Nov. 11, 2011 ON Semiconductor has expanded its portfolio of Constant Current Regulators (CCRs) to include the NSI50350A.

A constant current source with an LM317 voltage regulator is used as the main measuring circuit. The circuit in the following figure ensures that the current at OUT and through the diode will be ...

In 10k quantities, the AL5809 Constant Current Linear LED Driver from Diodes Incorporated is priced at: $0.10 USD each for the SOD-123 packaged devices, $0.11 USD each for the 15-50mA parts in the ...

This paper deals with the fundamentals of resonant regulators for constant current, and compares them with other kinds of regulators. It also discusses the various forms such regulators may take, ...
