LP02UC Series www.murata-ps.com Unregulated 2.25 Watt Dual-In-Line DC/DC Converter FEATURES DESCRIPTION RoHs compliant The LP02UC 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. 24-Pin DIP package Internal filtering Low output noise The LP02UC Series is housed in an industry standard 24-pin dual-in-line (DIP) package to permit upgrading of existing systems. Temperature Range: -25°C to +70°C A 100kHz push-pull oscillator is used in the input stage, complementing the unit's high efficiency and low noise characteristics. Surface mount construction Cheapernet Local area networks (LANs) The LP02UC 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 reflow-soldered, eliminating any hand-soldering during construction. This dramatically reduces unit variation and improves reliability. MECHANICAL: PACKAGE/PINOUT "K" THROUGH-HOLE SOLDERING INFORMATION APPLICATIONS Ethernet adapter cards These devices are intended for wave soldering or manual soldering. They are not intended to be subject to surface mount processes under any circumstances. PIN CONNECTIONS FUNCTION LP02UC TOP +VIN VIEW -VIN PINS The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of no more than 10 seconds. Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures within the converter will not exceed 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering. 1 & 24 12 & 13 +VOUT 11 & 14 -VOUT 10 & 15 NOTES: All dimensions are in inches (millimeters).
