NAME

FUNCTION

1

ZCD_EN#

The ZCD_EN# pin enables or disables Diode Emulation. When ZCD_EN# is LOW, diode

emulation is allowed. When ZCD_EN# is HIGH, continuous conduction mode is forced.

ZCD_EN# can also be put in a high impedance mode by floating the pin. If both ZCD_EN#

and PWM are floating, the device shuts down and consumes typically 3 μA (9 μA max.)

current.
