ZXSC100X8 Obsolete Closest Alternative is ZXSC100N8 ZXSC100 SINGLE CELL DC-DC CONVERTER SOLUTION The ZXSC100 series is designed for DC-DC applications where step-up voltage conversion from very low input voltages is required. These applications mainly operate from single nickel cadmium or nickel metal hydride battery cells. The circuit can start up under full load with regulation maintained down to an input voltage of only volts. The solution configuration ensures optimum efficiency over a wide range of load currents. Several circuit configurations are possible with loads up to 2W. The step up output voltage is easily programmed with external resistors. With its nonsynchronous architecture an output voltage down to the input voltage level can be achieved. For best performance the ZXSC100 quiescent current is a small 150uA ensuring minimum battery drain in no load conditions. The IC and discrete combination offers the ultimate cost vs. performance solution for single cell DC-DC conversion. Pin Assignments SO-8 • Efficiency maintained over a wide range of input voltages and load currents 82% efficiency VBATT = 1V • Startup under full load • Minimum operating input voltage VBATT = 0.926V • Adjustable output voltage down to VBATT • Quiescent current typically 150uA referred to input voltage • SO-8 package in “Green” Molding Compound No Br, Sb with lead Free Finish/RoHS Compliant Note 1 EU Directive 2002/95/EC RoHS .

Connect to RE in lower power applications. Must be unconnected in higher power applications. Only used if increased drive current to the main external NPN switching transistor is required. See Note Drive current sense input. Internal threshold voltage set 25mV below VCC. Connected external sense resistor. Note 2 Supply voltage, generally NiMH, NiCd single cell. ISENSE Inductor current sense input. Internal threshold voltage set to 25mV. Connect external sense resistor. Feedback sense. Internal threshold set to 730mV. Connect external resistive divider to output voltage. GND Ground Drive output for external switching transistor. VDRIVE Connect to base of external bipolar transistor. For increased drive current see Note 2 Note: In higher load current applications an additional PNP can be used to increase the drive current of the main external NPN switching transistor. The PNP base should be connected to BAS pin, its emitter to the RE pin and its collector connected to VDRIVE pin.
