Hello everybody .
I have a laptop psu delivering 19 v and 4.7 amp .
Now i need to replace a battery charger PSU but the original one was delivering a 10 v / 1.5-2A at the output . also the 10 volts was regulated with the tl431 , and the psu was used to charge a 9.6 v/ 3800 mah battery pack .
Is there a way to get the same output from a laptop PSU ( 19v/4.7A) using the tl431 or any other regulator but getting at least 1.5 A ??
