wwwDESCRIPTIONS
mThe 300WFS series 3 watts power modules are high
oefficiency, surface mount dc-dc converters that operate over a
wide input voltage range of 9 - 18 VDC, 18 - 36 VDC and 36 - 75
.cVDC and provide precisely regulated output voltages of 3.3V,
5V, 12V, 15V, ±5V, ±12V and ±15V.
The -40oC to +71oC operating temperature range makes it
Uideal for data communication equipment, mobile battery
driven equipment, distributed power systems, telecommunication
t4equipment, mixed analog/digital subsystems, process/
machine control equipment, computer peripheral systems
eand industrial robot systems.
