Absolute maximum ratings

Supply voltage of the device. A small bypass capacitor (0.1 µF typ.) to GND,

located as close to the IC’s pins as possible, might be useful to get a clean

supply voltage.

6OUT1

Open-drain output of the internal op-amp, whose non-inverting input is

the branch of the optocoupler’s photodiode to transmit the error signal to the

primary side for voltage control loop.

7OUT2

Open-drain output of the internal op-amp, whose non-inverting input is

the branch of the optocoupler’s photodiode to transmit the error signal to the

primary side for current control loop.

8Data

This pin will be externally pulled up to 3.6 V max

A small internal pull-up is present to prevent false signal detection (the pin is

floating during normal operation).
