DESCRIPTION

The LP02U Series is designed specifically for low-cost Local

Area Network applications. It provides isolated power for LAN

transceiver devices. The product operates from either 5 or 12

volts input voltage and supplies an isolated -9 volts output.

The LP02U Series is housed in an industry standard 24-pin dual-

in-line (DIP) package to permit upgrading of existing systems.

A 100kHz push-pull oscillator is used in the input stage,

complementing the units high efficiency and low noise charac-

teristics.

The LP02U Series offers the user a cost effective solution

without sacrificing reliability. A highly auto-

mated manufacturing process is employed in

which all components are surface mounted and

reflow-soldered, eliminating any hand-solder-

ing during construction. This dramatically re-

duces unit variation and improves reliability.
