Description
This pin connects directly to the rectified ac line voltage source. Internally Pin 1 is tied to the drain
of a high voltage startup MOSFET. During startup, the MOSFET supplies internal bias, and
charges an external capacitor that connects from the V CC pin to ground.
This pin has been omitted for increased spacing between the rectified AC line voltage on Pin 1
and the V CC potential on Pin 3.
This is the positive supply voltage input. During startup, power is supplied to this input from Pin 1.
When V CC reaches the UVLO upper threshold, the startup MOSFET turns off and power is sup-
plied from an auxiliary transformer winding.
These pins are the control circuit grounds. They are part of the IC lead frame and provide a ther-
mal path from the die to the printed circuit board.
Resistor R T connects from this pin to ground. The value selected will program the Current Limit
Comparator threshold and affect the Oscillator frequency.
Capacitor C T connects from this pin to ground. The value selected, in conjunction with resistor R T ,
programs the Oscillator frequency.
This 6.5 V output is available for biasing external circuitry. It requires an external bypass capacitor
of at least 1.0 m F for stability.
This pin is the Error Amplifier output and is made available for loop compensation. It can be used
as an input to directly control the PWM Comparator.
This is the inverting input of the Error Amplifier. It has a 2.6 V threshold and normally connects
through a resistor divider to the converter output, or to a voltage that represents the converter
output.
This input provides runaway output voltage protection due to an external component or connec-
tion failure in the control loop feedback signal path. It has a 2.6 V threshold and normally con-
nects through a resistor divider to the converter output, or to a voltage that represents the con-
verter output.
These pins have been omitted for increased spacing between the high voltages present on the
Power Switch Drain, and the ground potential on Pins 12 and 13.
This pin is designed to directly drive the converter transformer and is capable of switching a maxi-
mum of 500 V and 2.0 A.
