3 / 9 page Confidential Datasheet Version 1.0 July 2015. Revision 1.0 MagnaChip Semiconductor Ltd. 3 Pin Configuration Pin Definitions Pin# Name Description 1 COMP Compensation Pin for Error Amplifier. Connect a series RC from COMP to GND. 2 FB Feedback. The FB regulation voltage is 1.25V nominal. Connect an external resistive voltage divider between the step-up regulator ’s output(VOUT) and GND, with the center tap connected to FB. Place the divider close to the IC and minimize the trace area to reduce noise coupling. 3 EN Chip Enable. Drive EN low to turn off the Boost 4,5,11 (Exposed Pad) GND Ground. The Exposed Pad must be soldered to a large PCB and connected to GND for maximum power dissipation. 6,7 LX Switch. LX is the drain of the internal MOSFET. Connect the inductor/rectifier diode junction to LX and minimize the trace area for lower EMI. 8 VOUT Boost Converter Over Voltage Protection input. Bypass VOUT with a minimum 1uF ceramic capacitor directly to GND. 9 VIN Supply Input. Bypass VIN with a minimum 1uF ceramic capacitor directly to GND. 10 SS Soft-Start Control. Connect a soft-start capacitor(CSS) to this pin. The soft-start capacitor is charged with a constant current of 5uA. The soft-start capacitor is discharged to ground when EN is low Absolute Maximum Ratings Parameter Value Unit LX, VOUT to GND -0.3V to 28V V VIN, EN, SS, FB to GND -0.3V to 16.5V V COMP to GND -0.3V to 6.0V V Junction Temperature Range -40 to +150 ℃ Storage Temperature Range -65 to +150 ℃ Package Thermal Resistance (JA) 65.9 ℃/W Power Dissipation (Ta=25℃) 1.517 W Human Body Model(HBM) 2 kV Machine Model(MM) 200 V Charged Device Model (CDM) 700 V Note: Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Recommended Operating conditions Ambient Temperature Range -40 to +85 ℃ Junction Temperature Rnage -40 to +125 ℃ Exposed PAD COMP FB EN GND GND LX VOUT VIN SS LX 11 1 2 3 4 5 6 7 8 9 10 3mm x 3mm Ultra thin DFN-10 (Top view) |
