PIN FUNCTION DESCRIPTION
á
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. By inserting a resistor in series with the pin,
you control the amount of ramp compensation you need.
4
GND
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 22 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.
