Product Data Sheet UNREGULATED 2.25 WATT DUAL-IN-LINE DC/DC CONVERTER LP02U FEATURES q 24-PIN DIP PACKAGE q INTERNAL FILTERING q LOW OUTPUT NOISE q TEMPERATURE RANGE: -25°C TO +70°C q SURFACE MOUNT CONSTRUCTION APPLICATIONS q ETHERNET ADAPTER CARDS q CHEAPERNET LOCAL AREA NETWORKS (LANs) 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 dualin-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 characteristics. MECHANICAL PACKAGE/PINOUT "K" LP02U TOP VIEW The LP02U Series offers the user a cost effective solution without sacrificing reliability. A highly automated manufacturing process is employed in which all components are surface mounted and PIN CONNECTIONS reflow-soldered, eliminating any hand-solderFUNCTION PINS ing during construction.
