Part Number: TPA3255
Hello E2E Experts,
I use TPA3255's PBTL mode to build a 480w audio amplifer. When power up, no signals input to TPA3255, PVDD = 48V, GVDD=VDD= 12V, DVDD=3.3V, AVDD=7.74V, VBG=1.2V, the pin CLIP_OTW keeps low, the pin Fault keeps high. When the differential sigal inputs to TPA3255, the CLIP_OTW keeps low , TPA3255 can't work. Please help to check the schematic.
Regards,
