    i know some having problem with high voltage at output when using ir2153 because this chip dont have softstart, but we can solved it by make softstart circuit directly from 220 vac using few components and relay, ill post new picture soon, i have made new one but this time im ordering pcb lol from jlcpcb because its cheap, and i solved the peak startup of ir2153 and its running very smooth and smart, btw its 50% all the time duty cycle, if we want external aux we can use simple tny chip ie tny264 can maxed up to 300ma for 12vdc or we can get more current with tny268 with same circuit just change the chip, this chip has internal protection, overvoltage, overcurrent, short circuit, over temp, and i already terstg it ofc none of my tny burn and its very simple circuit also, so when i do this post means all thing has been ready setup and complete but i still have alot of pcb board because 1 order i get 10pcs, so i do setup with irs2153 v.out +- 67 vdc to pull 2 irs2092 rated at 250w 8 ohm, and irs2153 v.out 27vdc to pull tpa311d62 100w+100w, so all of them good with softstart, ill take picture and video soon here.
