Their marketing dept turned its technical fault into a "feature".zachtheterrible said:It did say though that it mimics an incandescent bulb in that it gets dimmer and dimmer. What's the point of that?
Zach, I couldn't find a statement to that effect. Where is it?zachtheterrible said:It did say though that it mimics an incandescent bulb in that it gets dimmer and dimmer.
Ah, OK. I stupidly had gone to the datasheet of the 3021 buck puck - since that is what I was searching for. I see that it costs a lot more, and requires a higher voltage supply. Good reasons for looking at the 2009-H.audioguru said:Hi Ron,
Google 3021 buck puck.
Their Model #2009-H driver dims the LED as the battery voltage drops. :lol:
HAAA HAA HA!! :lol:Their marketing dept turned its technical fault into a "feature".

My laptop was ruined when I left it unused for a year. The NiCd battery CMOS backup is of the type that soldered to the motherboard, can't remove it. The leaked electrolyte destroyed the fine tracks to and under surface mounted ICs. I washed the board in water but nothing would help.
