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.
