Hi! The combination of a boosting DC/DC converter and a constant-
current regulator in a single IC seems popular for driving strings of
LEDs, especially for a low voltage input (say 12 volt) and a long
string of LEDs which need a high current. Has anybody got any
recommendations on what chip to use ? It is difficult to find these
among the dozens of similar IC's with multiple channels, dimming, too
low current or too low output-voltage etc.
So far I have one from Maxim called 16818 and a National part, LM5000
as candidates..
Best regards,
Bjorn
