Hello,
D1 Zener diode tries to clamp VCC2 driven by DLPA200's Voffset in appropriate voltage range
BZD27C8V2P has following tolerance between 7.7 V to 8.7 V.
If the tolerance goes min, the VCC2 becomes less than 8.25V.
So, would you tell me why this circuit work ?
Our customer would like to know this reason for their mass-production design safe.
