SEMICO NDUC TORS

DESCRIPTION

The ZXSC410 is voltage mode boost converter in SOT23-6 package. Its excellent

load and line regulation means that for the full supply range from lithium Ion cells,

the output voltage will typically change by less than 1%. Using high efficiency

Zetex switching transistors allow output voltages of tens of volts depending on the

selected transistor. The ZXSC420 includes a battery low indicator. This operates

by indicating when the converter is no longer able to maintain the regulated

output voltage rather than setting a preset threshold, thereby making it suitable for

various battery options and load currents.
