dna1002

Hi,

I'm looking for informations on Delta DNA1002 Chip, It's a 16 pin component
I think it's a comparator or something like that.
I'm looking for a datasheet.
Many thanks.

Regards,

Ulrich
 

dna 1002

DNA1002 always found in Delta PC power supply. Delta has her own custom made "PWM power source management integrated circuit", which formed by DNA1002 and DNA1004 (in some Delta power supply).

According to the following link: **broken link removed** (but in Chinese), DNA1002 is a PWM controller.

But according to the following link: http://ly.beareyes.com.cn/cgi-bin/liuyan_work.pl?job=see&id=20020709108&who=bear (but in Chinese), DNA1002 is a power supply supervisory IC.
 

dna1002 datasheet

Many thanks,
But information is missing...
I have some trouble with a delta specific power supply.
I mean when starting 12v output falls bellow 11.7V and I see a 1 on a latch pin leaving a DNA1002 chip. And a security stop the power supply
I 'd like to modify the comparaison value in order to enable my 12V output
anyone has an idea?
regards,
