Rating
Positive input supply voltage. This pin is connected to an external capacitor for energy storage.
The startup circuit sources current out of this pin to initially charge the capacitor. When the
voltage reaches the upper threshold limit of the undervoltage lockout circuit, the startup circuit
will turn off, and the power supply will begin operation. Power is then supplied to the chip via
this pin, by virtue of the auxiliary winding.
The error signal from the optocoupler is fed into this input. It is loaded with a 2.7 kΩ resistor
which converts the opto current into a voltage. There is a 7.0 kHz, single pole, low pass filter
between this pin and the error amp input. A 10 volt clamp is also connected to this pin to protect
the device from ESD damage or overvoltage conditions.
Ground reference pin for the circuit. These pins are part of the integrated circuit leadframe and
are an integral part of the heat flow path on the PDIP--8 package.
This pin is connected to the bulk DC input voltage supply. It feeds an internal current source that
initially charges up the V
The internal power switch circuit is connected between this pin and ground. This pin connects
directly to one end of the transformer primary winding.
