Auto-OCP/Fan Curve
What Can do about Auto OCP?
- Traditional manufacture flow
- INT set 20A level (for example) artificial regulate VR to latch mode glue fix
- Drawback
- VR regulate need additional main-power
- ageing
- Glue crack, VR loose, ….etc
- Proposal
- Supervisor integrate Infinno Smart-auto-trim™ algorithm
- Change VR stage to IC auto trim test methodology
- Advantage (Automation)
- Keep current manufacture flow
- Skip the risk of ageing of VR
- Skip OCP regulation time
- Traditional manufacture flow
What Can do about Auto Fan?
- Auto Fan curve setting
- Auto Fan Curve Design Tool
- Online fan curve adjusted
- Easy fan curve debug by debug mode
