General Description
The front end of FI5 89 W series is a highly efficient DC/DC to provide a wide input of volt age range. The back end is a constant current LED driver which can drive a number of LEDs in series & parallel configurations.
Features
- Wide input rang: DC 12V
- Provide output Typ. 1.28 W.
- Flexible digital(PWM) for dimming control.
- The Soft start function minimizes inrush current while powering up.
- Multiple LED Protections
- LED Open Short protection
- Over-current Limit protection
- Over temperature protection
- Over-voltage protection
- Under voltage lockout (UVLO)
- Low profile and lightweight: 88 mm(L) x 32 mm(W) x 9.2 mm(H).
- RoHS Compliant.
