1 / 17 page  ZXSC100 SEMICO NDUC TORS ISSUE 3 - JANUARY 2004 1 DESCRIPTION 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 0.926 volts. The solution configuration ensures optimum efficiency over a wider range of load currents, several circuit configurations are possible with power dissipation up to 2W. The step up output voltage is easily programmed with external resistors, the non-synchronous architecture and SuperSOT4™ device enabling an output voltage down to the input voltage level. For best performance the ZXSC100 quiescent current is a small 150µA 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. SINGLE CELL DC-DC CONVERTER SOLUTION FEATURES • Efficiency maintained over a wide range of input voltages and load currents 82% efficiency @ V BATT=1V • Startup under full load • Minimum operating input voltage V BATT=0.926V • Adjustable output voltage down to V BATT • Quiescent current typically 150µA referred to input voltage • MSOP8 package • SO8 package APPLICATIONS • Cordless telephones • MP3 players • PDA • Pagers • Battery backup supplies • Electronic toothbrush • GPS receivers • Digital camera • Palmtop computers APPLICATIONS(continued) • Hand held instruments • Portable medical equipment • Solar powered equipment Q1 FMMT617 R2 R1 L1 D1 ZHCS1000 R3 R4 C2 C1 3.3V/0.1A BAS EM RE VBATT VCC GND FB ISENSE VDRIVE U1 ZXSC100 C3 TYPICAL APPLICATION CIRCUIT ORDERING INFORMATION DEVICE Package Partmarking Reel size Tape width Quantity per reel ZXSC100X8 MSOP8 ZXSC100 7” 12mm 1,000 ZXSC100N8 SO8 ZXSC100 7” 12mm 500 |
