Inverting input of the voltage loop op amp. The pin will be tied to the mid-point
of a resistor divider that senses the output voltage.
Ground. Return of the bias current of the device. 0 V reference for all
voltages. The pin should be tied as close to the ground output terminal of the
converter as possible to minimize load current effect on the voltage regulation
set point.
Common open-drain output of the two internal op amps. The pin, able to sink
current only, will be connected to the branch of the optocoupler’s photodiode
to transmit the error signal to the primary side.
Non-inverting input of the current loop op amp. It will be tied directly to the hot
(negative) end of the current sense resistor
Inverting input of the current loop op amp. The pin will be tied to the cold end
of the current sense resistor through a decoupling resistor.
Supply Voltage of the device. A small bypass capacitor (0.1 µF typ.) to GND,
located as close to IC’s pins as possible, might be useful to get a clean
supply voltage.
