DESCRIPTION

The LP02UC Series is designed specifi cally for low-cost Local Area Network applications. It provides isolated power for LAN transceiver devices. The prod- uct operates from either 5 or 12 volts input voltage and supplies an isolated -9 volts output. The LP02UC 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 unit's high effi ciency and low noise characteristics. The LP02UC Series offers the user a cost effective solution without sacrifi cing reliability. A highly automated manufacturing process is employed in which all components are surface mounted and refl ow-soldered, eliminating any hand-soldering during construction. This dramatically reduces unit variation and improves reliability. NOTES: All dimensions are in inches (mil- limeters). PIN CONNECTIONS FUNCTION PINS +VIN 1 & 24 -VIN 12 & 13 +VOUT 11 & 14 -VOUT 10 & 15 MECHANICAL: PACKAGE/PINOUT "K"

APPLICATIONS

Ethernet adapter cards Cheapernet Local area networks (LANs)

FEATURES

RoHs compliant 24-Pin DIP package Internal fi ltering Low output noise Temperature Range: -25°C to +70°C Surface mount construction SIDE VIEW TOP VIEW SIDE VIEW LP02UC ISO9001 CERTIFIED These devices are intended for wave soldering or manual soldering. They are not intended to be subject to surface mount processes under any circumstances. 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.
