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.

bsolute Maximum Ratings are stress ratings. Stresses in excess of these
ratings can cause permanent damage to the device. Functional operation of the
device at these or any other conditions beyond those indicated in the operationa

ESD Warning
ESD (electrostatic discharge) sensitive device. Although the IXI858 / IXI859 feature proprietary ESD protection circuitry, permanent
damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD precautions are recommended to avoid
performance degradation or loss of functionality.
