DESCRIPTIONS
The 200WFR series are low-profile 2 watts dc-dc converters
that operate over input voltage ranges of 4.5 to 9VDC and 9 to
18VDC, 18 to 36VDC and 36 to 75 VDC and provide precisely
regulated output voltages of 3.3V, 5V and 12VDC.
The -40^oC to +65^oC operating temperature range makes it
ideal for data communication equipment, mobile battery
driven equipment, distributed power systems, telecommunication
equipment, mixed analog/digital subsystems, process/
machine control equipment, computer peripheral systems
and industrial robot systems.
