PIN NAME DESCRIPTION 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 capacitor CT to ground. Operation to 500 kHz is possible. 5 GND 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 1.0A 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. BLOCK DIAGRAM |
