I have designed an electronic circuit and am using the LTC3638 in the Output Voltage Programming mode. The circuit and configure so that it operates a 120 AVC at the input and 11 volts at the output. May I have problems the circuit works fine when I apply 120v on the input and have 10.98volts on the output. The problem is when I apply a load which is a single LED the circuit stops working and I have to replace the LTC3638. See the schematic
Thank you for your help!
