Description
Regulating voltage : information input concerning secondary voltage.
By comparing the regulating voltage obtained from the regulating winding of the transformer with the
internal reference voltage, the output pulse width on Pin 5 is adaptedto the load of the secondary side
(normal, overload, short circuit, no load)
Primary currentsimulation : information input regarding the primary current. The primary current rise in the
primary winding is simulated at Pin 2 as avoltage rise by means of external RC element. When avalue is
reached that is derived from the regulating voltage at Pin 1, the output pulse at Pin 5 is terminated.The
RC element serves to set the maximum power at the overload point.
Primary voltage detector : input for primaryvoltage monitoring. When the line voltage is too low the IC is
switched-off by comparing V
3
with an internal reference. Voltage at Pin 3 is used for overload point
compensation.
Ground
Output : push-pull output for charge and discharge of the gate capacitance of the power MOS transistor.
Supply voltage : Supply voltageinput. From itare deriveda stable internal reference voltage (V

Soft-start : input for soft-start and integrationnetwork. Start-up will begin with short pulses by connecting a
capacitor between Pin 7 to ground. This capacitor together with a resistor connected between Pin 7and
error amplifier output also as acts an integrator network for regulation.
Zero detector : Input for the oscillator feedback. After starting oscillator, every zero transit of the feedback
voltage (falling edge) triggersan output pulse at Pin 5.The trigger threshold is at typically - 50mV
