DESCRIPTION

The LP02UC Series is designed specifically 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 efficiency and low noise characteristics.

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.

NOTES:

All dimensions are in inches (mil-

limeters).

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.
