Description

The ZXSC410 is voltage mode boost converter in SOT26 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.

Feature(s)

  • 1.65V to 8V supply range
  • Typical output regulation of ±1%
  • Over 85% typical efficiency
  • Output currents up to 300mA
  • 4.5μA typical shutdown current ZXSC410
  • End of regulation output ZXSC420
  • Application(s)

  • System power for battery portable products
  • LCD bias
  • Local voltage conversion
