3 / 9 page Current Mode PWM Controller 3 PIN FUNCTION N FUNCTION DESCRIPTION 1 COMP This pin is the Error Amplifier output and is made 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 capacitor CT to ground. 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 sink by this pin. 7 VCC This pin is the positive supply of the integrated circuit. 8 Vref This is the reference output. It provides charging current for capacitor CT through resistor RT . APPLICATION INFORMATION Figure 1. Error Amp Configuration Figure 2. Undervoltage Lockout KA3843A(AM) WS WS |
