I am working on a power supply for a smart LED lamp. The ouput requirements are: 300mA @ 25V. I used PI Expert to design the circuit based on the TNY285. My prototype works well, but I have a problem getting the device to work in C.C. mode. I made 2 observations:
1. the power supply supplies a lot more current that the designed requirement of 300mA at 25V.
2. When peak power is achieved the device resets.
Am I missing something basic? What is the way to adjust the output power without having the device reset?
Thanks in advance for your help.
