Part Number	NCP1203 Datasheet
Manufacturer	onsemi
Overview	Pin No. Pin Name Function 1 Adj Adjust the skipping peak current 2 FB Sets the peak current setpoint 3 CS Current sense input 4 GND The IC ground 5 Drv Driving pulses 6 VCC 7 NC . a high *voltage startup FET which ensures a clean and loss *less startup sequence. Its current *mode control naturally provides good audio *susceptibility and inherent pulse *by *pulse control. When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatical.
