I wonder if you have any power supply design switched to power leds 300W. Since I am using only 01 led 300W, I need a power supply with constant current, 33V x 9A. To have some solutions, but they are not components of ON. If you can help me I thank you. Regards, Barone.
Please refer to our evaluation kit with NCP1397 as an example for your application.The Boost PFC stage employs ON Semiconductor's NCP1654 CCM controller. The second stage is an isolated DC-DC converter that converts the 385 V dc bus to a 12 V dc voltage output and employs ON Semiconductor’s NCP1397 LLC controller.
You need to design external components according your output voltage and current ( 33V x 9A.)
In addition to this EVK schematic you can implement NCP1002A for LED Switching Mode Power Supply (SMPS) applications requiring a dual
control loop to perform Constant Voltage (CV) and Constant Current (CC) regulation.
