General Description
The IXI858 and IXI859 combine a power MOSFET
driver, linear voltage regulator, and charge pump
regulator for power supply generation in a single
SOIC-8 package. The IXI858 features a 5.0V linear
voltage regulator, and the IXI859 a 3.3V linear
voltage regulator. These three power functions
combined on the IXI858/859 target micro-controller
based off-line applications.
The IXI858 and IXI859 are designed to operate over
a temperature range of -25°C to +125°C, and are
available in an 8 lead SOIC package.
