CYStech Electronics Corp. Spec. No. : C510Q8-A Issued Date : 2003.08.12 Revised Date : Page No. : 2/15 PL384XAQ8 CYStek Product Specification Absolute Maximum Ratings Symbol Parameter Value Unit VI Supply Voltage (low impedance source) 30 V VI Supply Voltage (Ii<30mA) Self Limiting IO Output Current ± 1 A EO Output Energy (capacitive load) 5 µJ Analog Inputs (pins 2, 3) -0.3 to 5.5 V Error Amplifier Output Sink Current 10 mA Ptot Power Dissipation at Tamb≤ 25℃ 1.25 W Tstg Storage Temperature Range -65 to +150 ℃ TJ Junction Operating Temperature -40 to +150 ℃ TL Lead Temperature (soldering 10s) 300 ℃ Note : All voltages are with respect to pin 5, all currents are positive into the specified terminal. Pin Connection (top view) Pin Functions No Function 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 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. Thermal Data Symbol Description Value Unit Rth, j-amb Thermal Resistance, junction to ambient 150 ℃ /W COMP VFB ISENSE RT/CT VREF VCC OUTPUT GROUND |
