Hi, I need someone who knows a little about LM350 voltage regulators...
I'm referring to the data sheet on this website:
http://www.national.com/ds/LM/LM150.pdf
*** Page 10 - "12V Battery Charger" ***
Can anyone please explain to me briefly how the above circuit works?
I want to charge a small 12V SLA battery. I'm guessing this circuit
senses
the battery's condition and perhaps controls the way the LM350 behaves,
no?
(snip)
If you really want to charge a SLA battery, I'd suggest using a smarter
circuit/device - have a look at the Unitrode (now TI) UC3906 at:
http://focus.ti.com/lit/ds/symlink/uc3906.pdf
One more thing I need to check. I have a 18V DC 1.2A regulated adaptor,
but
I want to charge a 12V 1.3A battery (Jaycar part # SB-2480) .... would i
just need to increase the resistance of R7?
That adaptor would be quite suitable for a charger based on the UC3906.
There
was a ?SC kit using them - may still be around ay Jaycar, Altronics or
TrickieDickie's.
