Pin Name
Function
Pin Description
1
Adj
Adjust the skipping peak current
This pin lets you adjust the level at which the cycle skipping process takes
place. Shorting this pin to ground, permanently disables the skip cycle
feature.
2
FB
Sets the peak current setpoint
By connecting an optocoupler to this pin, the peak current setpoint is
adjusted accordingly to the output power demand.
3
CS
Current sense input
This pin senses the primary current and routes it to the internal comparator
via an L.E.B.
4
GND
The IC ground
5
Drv
Driving pulses
The driver’s output to an external MOSFET.
6
V
CC
Supplies the IC
This pin is connected to an external bulk capacitor of typically 10 F.
7
NC
This unconnected pin ensures adequate creepage distance.
8
HV
Generates the V
CC
from the line
Connected to the highvoltage rail, this pin injects a constant current into
the V
CC
bulk capacitor.
