I have attached the file of RDR-291 150 Watt LED driver by Power Integration i have made a board and tested it for 2 times i got to know some points. Now i am giving here to get clarify my doubts.
1. When i connected a LED load ( 30V forward voltage ) to one channel with 2nd channel got opened...
can i change the output current from 2.1A to 2.7A by increasing the Feedback pin Resistor value? the actual output current is 2.1A and the feedback resistance value in the design is 95.3 K ohm . can i increase the Resistor value to 110 K ohms or higher to get the output current 2.7 A.
And Can...

Hi,
i am Murali Krishna new to Real time work i am trying to develop a 150W LED driver, I have a reference design for "Power Integrations " i.e RDR 291. its operating input voltage is (184-275)v AC but i want to make it (90-265)V AC, so can anyone suggest me what hardware changes makes me...
