SSL4120

Resonant power supply controller IC with PFC for LED lighting

[1]

The marked levels on this pin are correlated. The voltage difference between the levels has much less spread than the absolute value of

the levels themselves.

[2]

Switching level has some hysteresis. The hysteresis falls within the limits.

For a typical application with a compensation network on the COMPPFC pin, as the example in Figure 19.

Minimum time required between demagnetization detection and

V/t = 0 on the SNSAUXPFC pin.
