2 / 5 page IL3842 2011, February, Rev. 03 PIN FUNCTION DESCRIPTION Pin No. Function Description 1 Compensation This pln is the Error Amplifier output and is made available for loop compensation 2 Voltage Feedback This is the inverting input of the Error Amplifier. It is normally connected to the switching power supply outpul through a resistor divider. 3 Current Sense 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 500kHz is possible. 5 GND This pin is the combined conlrol 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 chsarging current for capacitor CT through resistor RT ABSOLUTE MAXIMUM RATINGS Characteristic Symbol Value Unit Total Power Supply and Zener Current (ICC+ IZ) 30 mA Output Current IO ±1.0 A Output Energy (Capacitive Load per Cycle) W 5.0 µJ Error Amp Output Sink Current IOE 10 mA Current Sense and Voltage Feedback Inputs Vin -0.3 to 5.5 V Maximum Power Dissipation @ TA= 25 oC: DIP-8 SOP-8 PD 0.862 0.625 W Thermal Resistance,Junction-to-Air RθJA 145 °C/W Operating Junction Temperature TJ +150 oC Storage Temperature Range Tstg -65 ~ +150 oC * Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. |
