Electrical Characteristics

Note 3: AP3700/A is an emitter drive controller, the PWM controller will start up only when the voltage on the OUT pin rises up to its threshould value. Note 4: AP3700/A performs its short circui t function by shutdown the OUT pulse when the OUT pin voltage drops below its short circuit threshold value.
