BOK
Bulk OK
This pin detects the input line voltage by sensing the bulk capacitor, and
disables the PWM when line voltage is lower than normal.

Description
2
FB
Sets the Peak Current Setpoint
By connecting an optocoupler to this pin, the peak current setpoint is ad-
justed according to the output power demand. Internal monitoring of this
pin level triggers the fault management circuitry.
3
CS
Current Sense Input
This pin senses the primary inductor current and routes it to the internal
comparator via an LEB circuit.
4
GND
The IC Ground
5
DRV
Driving Pulses
The driver’s output to an external MOSFET.
6
VCC
Supplies the IC
This pin is connected to an external bulk capacitor of typically 10 F.
7
NC
No Connection
This unconnected pin ensures adequate creepage distance between High
Voltage pin to other pins.
8
HV
Generates the V
CC
from the Line
Connected to the highvoltage rail, this pin injects a constant current into
the V
CC
capacitor.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. This device series contains ESD protection and exceeds the following tests:
Human Body Model (HBM) > 2.0 kV per JEDEC standard: JESD22A114.
Machine Model (MM) > 200 V per JEDEC standard: JESD22A115.
