Pin Function Description

Vstr
This pin connects directly to the rectified AC line voltage source. At start up
the internal switch supplies internal bias and charges an external capacitor
that connects from the Vcc pin to ground. once this reaches 8.7V, Vstr is
isolated internally.
This pin is the inverting input of the PWM comparator, and it operates
normally between 0.5V and 2.5V. It has a 0.45mA current source
connected internally and a capacitor and opto coupler connected
externally. A feedback voltage of 3.5V to 4.5V triggers overload protection
(OLP). There is a time delay due to the 5uA current source, which prevents
false triggering under transient conditions but still allows the protection
mechanism to operate under true overload conditions.
These pins are the control ground and the SenseFET Source.
This is the positive supply voltage input. During start up, power is supplied
to this input from Pin 1. When Vcc reaches the UVLO upper threshold
(8.7V), the start up Internal Switch (Vstr) turns off and power is supplied
from auxiliary transformer winding.
This pin is designed to directly drive the converter transformer and is
capable of switching a maximum of 650V and 1A.
