ZCV (Zero Crossing)
At this pin, the voltage from the auxiliary winding after
a time delay circuit is applied. Internally, this pin is
connected to the zero-crossing detector for switch-on
determination. Additionally, the output overvoltage
detection is realized by comparing the voltage Vzc with
an internal preset threshold.
VR (Voltage Sense)
The rectified input mains voltage is sensed at this pin.
The signal is used to set the peak current of the peak-
current control and therefore allow for the PFC and
phase-cut dimming functionality.
CS (Current Sense)
This pin is connected to the shunt resistor for the
primary current sensing, externally, and the PWM
signal generator for switch-off determination (together
with the feedback voltage), internally. Moreover, short-
winding protection is realised by monitoring the voltage
Vcs during on-time of the main power switch.
GD (Gate Drive Output)
This output signal drives the external main power
switch, which is a power MOSFET in most case.
HV (High Voltage)
The pin HV is connected to the bus voltage, externally,
and to the power cell, internally. The current through
this pin pre-charges the VCC capacitor with constant
current once the supply bus voltage is applied.
VCC (Power supply)
VCC pin is the positive supply of the IC. The operating
range is between V
