i am designing DOB LED light using IC CYT1000AEG. it is simple circuit only current sense resistor and one capacitor for buffer effect.
my rsense value is 28ohm for 20mA current and LED is 3 nos in series 9V. when i turn on input supply 230V AC my LED suddenly get damage.
what will be issue..?
attached schematic and IC datasheet for details. enter image description here
