Description
Ground reference pin for the circuit.
An external capacitor connected to this pin sets the oscillator frequency up to 1 MHz.
The oscillator can be synchronized to a higher frequency by charging or discharging
C T to trip the internal 3.0 V/3.5 V comparator. If a fault condition exists, the power
switch is disabled and the frequency is reduced by a factor of 7.
The regulated voltage is scaled down to 2.5 V by means of a resistor divider.
Regulation is achieved by comparing the scaled voltage to an internal 2.5 V reference.
Requires external compensation network between COMP and V FB pins. This pin is
effectively grounded if faults are present.
Line voltage (V in ) is scaled down using an external resistor divider such that the OV
voltage reaches 2.5 V when line voltage reaches its maximum operating voltage.
Line voltage is scaled down using an external resistor divider such that the UV
voltage reaches 2.5 V when line voltage reaches its minimum operating voltage.
This pin is connected to an external capacitor for energy storage. During Turn--On, the
startup circuit sources current to charge the capacitor connected to this pin. When the
supply voltage reaches V CC(on) , the startup circuit turns OFF and the power switch is
enabled if no faults are present. An external winding is used to supply power after
initial startup to reduce power dissipation. V CC should not exceed 16 V.
This pin directly connects the Power Switch and Startup Circuits to one of the
transformer windings. The internal High Voltage Power Switch Circuit is connected
between this pin and ground. V DRAIN should not exceed 200 V.
