● Hysteretic PFM
Hysteretic PFM control with fast response provides high dimming resolution.
● Adequate Protection
1. Techniques of failure protection including open/short-circuit, LED over current, over-temperature, and thermal fold back. 2. Extend protection over power system failure to production failure.
● Thermal Fold-back
The LED driver IC providing thermal foldback function coupled with the thermistor should have the capability to resolve the self-heating issue of the thermistor. In addition, the most important capability is the adjustability of the thermal foldback curve which include output current break point temperature (TFB) and cut-off temperature (T Cut-off) capable of arbitrarily adjusting the thermal foldback function with circuit design.
