IMS 25 Series

Functional Description
The IMS 25 series of DC-DC converters are magnetic feed-
back controlled forward converters using current mode
PWM (Pulse Width Modulation). The 2.5, 3.3 and 5.1 V out-
put voltage versions feature a synchronous rectifier result-
ing in very high efficiency. The output voltage of these ver-
sions can be adjusted via the Trim input. The Trim input is
referenced to the secondary side and allows for program-
ming of the output voltage in the range of approximately 80
to 110% of
Uo nom using an external resistor.
The voltage regulation is achieved with a magnetic feed-
back circuit providing excellent line and load regulation.
Current limitation is provided by the primary circuit, thus
limiting the total output current to approx. 1.0...1.4
Io nom
(see:
Type Survey). The shut down input allows remote
converter on/off.
Overtemperature protection will shut down the unit in ex-
cessive overload conditions with automatic restart.
