6. DIMMER COMPATIBILITY

The boost stage is a low-side asynchronous boost converter. Once the CS1680 reaches its UVLO start threshold

and begins normal operation, the CS1680 controller executes a dimmer switch detection algorithm to set the oper-

ating state of the IC. Table 1 summarizes the system operating state that produced the empirical dimmer compati-

bility results.

Notes: 1. Tested at nominal input voltage, nominal input frequency and without a dimmer

2. Tested over input voltage tolerances for steady-state operation

3. Compliant with IEC 61000-3-2 Class C < 25W

4. Average

5. Peak-to-peak

6. Measured with Chroma 66202 Power Analyzer

7. MR16 lamp efficiency is dependent on LED output voltage V
