Linear Technology has announced the LT3909, a high efficiency, constant current LED driver that can drive two strings of up to 10 LEDs at 50mA. To ensure constant brightness, each LED string contains ...
Solid state lighting solutions are increasing in popularity across a broad variety of illumination, indication, signage and backlighting applications, replacing traditional incandescent and ...
FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...
The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...
Fault protection is a critical function of all power supply controllers. Nearly all applications require some kind of over-load protection. For peak current-mode controllers this is easily ...
