VOLTAGE MODE BOOST CONVERTER
ZXSC410
ZXSC420
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.
FEATURES
• 1.65V to 8V supply range
• Typical output regulation of ±1%
• Over 85% typical efficiency
• Output currents up to 300mA
• 4.5␮A typical shutdown current ZXSC410
• End of regulation output ZXSC420
APPLICATIONS
• System power for battery portable products
• LCD bias
• Local voltage conversion
