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.
