ESCRIPTIONS
The 200VFI series is a family of cost effective 2 watt single
and dual output DC/DC converters. 18 models operate from
input bus voltages of 5V, 12V and 24V; producing output
voltage levels of 5V, 12V, 15V, ±5V, ±12V and ±15V for a wide
range of choices.
The 200VFI series is ideal for a variety of applications
including distributed power systems, mixed analog / digital
subsystems, portable test equipment, local power networks
and battery backed systems.
