SSL8516BT

Greenchip PFC and flyback controller

[1]

A typical application with a compensation network on the PFCCOMP pin, such as the example in Figure 3.

[2]

The clamp voltage on the PFCCOMP pin is dependent on the VINSENSE voltage. When the VVINSENSE rises above

Vth(sel)clmp +Vth(sel)clmp(hys), the high clamp level is active. When the voltage on the VINSENSE pin drops below the Vth(sel)clmp level

again, the low clamp level is active.
