Application Information
1
VCC
Power supply input
This pin provides power to the internal control circuitry and gate driver.
Connect a 10µF capacitor from this pin to ground.
Connect a 10µF capacitor from this pin to ground.

ZCD
Zero crossing detection input
The pin senses the voltage of the auxiliary winding for zero current
detection.
detection.
3
AGND
Small signal ground
Signal ground.
4
COMP
Compensation network
Output of the error amplifier. Connect a capacitor from this pin to
ground to set the frequency response of the LED current regulation
loop.
ground to set the frequency response of the LED current regulation
loop.
5
DLY
Delay control input
Connect a resistor from this pin to ground to set the delay between
switching ON and OFF periods.
switching ON and OFF periods.
6
MODE2
Mode selection input 2
Select operating mode for isolated or non-isolated mode.
7
MODE1
Mode selection input 1
Select operating mode for peak current mode or constant ON time.
