Function

This pin monitors the MOSFET current to limit its maximum current. This pin is

also connected to an internal comparator for zero current detection (ZCD). This

comparator is designed to monitor a signal from an auxiliary winding and to detect

the core reset when this voltage drops to zero. The auxiliary winding voltage is to

be applied through a diode to avoid altering the current sense information for the

on time (see application schematic).

Ground reference.

MOSFET driver. The high current capability of the totem pole gate drive (−0.5/

+0.8 A) makes it suitable to effectively drive high gate charge power MOSFETs.

Supply input. This pin is the positive supply of the IC. The circuit starts to operate

when VCC exceeds VCC(on). After start−up, the operating range is 9.5 V up to 28 V.

Removed for creepage distance.

This pin is the input for the line removal detection, line level detection, and

brownout detection circuits. For versions C and D, this pin is also the input for the

high voltage start−up circuit.
