UC3842各脚功能；
1 COMP This pin is the Error Amplifier output and is made available for loop compensation.
2 VFB This is the inverting input of the Error Amplifier. It is normally connected to the switching power supply output through a resistor divider.
3 ISENSE A voltage proportional to inductor current is connected to this input. The PWM uses this information to terminate the output switch conduction.
4 RT/CT The oscillator frequency and maximum Output duty cycle are programmed by connecting resistor RT to Vref and cpacitor CT to ground. Operation to 500kHz is possible.
5 GROUND This pin is the combined control circuitry and power ground.
6 OUTPUT This output directly drives the gate of a power MOSFET. Peak currents up to 1A are sourced and sunk by this pin.
7 VCC This pin is the positive supply of the control IC.
8 Vref This is the reference output. It provides charging current for capacitor CT through resistor RT.
