Pin setting

COMP

Compensation. It is the output of the internal E/A. A compensation network is

placed between this pin and GND to achieve stability and good dynamic

performance of the control loop. In case of secondary feedback, the internal E/A

must be disabled and the COMP directly driven by the optocoupler to control the

DRAIN peak current setpoint.

6 to 10

DRAIN

MOSFET drain. The internal high voltage current source sinks current from this

pin to charge the VCC capacitor at startup and during steady-state operation.

These pins are mechanically connected to the internal metal PAD of the

MOSFET in order to facilitate heat dissipation. On the PCB a copper area must

be placed under these pins in order to decrease the total junction-to-ambient

thermal resistance thus facilitating the power dissipation.
