Hi
I have a TDK-Lambda Z+ 36V / 12A Power supply. It shows fail, when the output is switched on. After swapping the control board from a borrowed good unit, and later swapping the IC A106 on the control board, the failure got resolved. It's a TSSOP with 508RP marking with ST logo. The ST website does not have any info regarding the same. No service manual is also available.
Need help on this.
Thanks for your time.
Regards
