Description
The FLS0116 LED lamp driver is a simple IC with integrated MOSFET and PFC function. The special “adopted digital” technique aut omatically detects input voltage condition and sends an internal reference signal to achieve high power factor. When AC input is applied to the IC, the PFC functi on is automatically enabled. When DC input is applied to the IC, the PFC function is automatically disabled. The FLS0116 does not need a bulk (electrolytic) capacitor for supply rail stability, which significantly improves LED lamp life. Figure 1. Typical Application

The devic e may not function or be operable above the recommended operating c onditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter Min. Max.
