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.

(millimeters).

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.
