PIN CONFIGURATION

Note:

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional

operation under these conditions is not implied. Continuous operation of the device at the absolute rating

level may affect device reliability.

Note:

1. ILED=0.6/REXT, VFF=0V, DIM=0V, LED=25V

2. VDROP=VIN－VLED, PD＜1W (No heat sink)

3. VREF=V(REXT), VFF=0V, DIM=0V

4. The current regulation is for an instantaneous AC line input current only, not to exceed thermal characteristics of package.
