DESCRIPTIONS
The LNB series are 10 watts low-profile dc-dc converters
that operate over input voltage ranges of 4.5 - 7 VDC, 8 - 16
VDC and 18 - 36 VDC, and provide precisely regulated output
voltages of 3.3V, 5V, 12V and 15V.
The -30^oC to +71^oC operating temperature range makes the
LNB series ideal for data communication equipments,
mobile battery driven equipment, distributed power systems,
telecommunication equipment, mixed analog / digital
subsystems, process/machine control equipment, computer
peripheral systems and industrial robot systems.
