Functional Description
The IMX7/IMS7 Series DC-DC converters are feedback-
controlled flyback converters using current mode PWM (Pulse
Width Modulation).
In the case of single-output models, the output is directly
sensed and fed back to the primary control circuit via a pulse
transformer, resulting in tight regulation of the output voltage.
The R input is referenced to the secondary side and allows for
programming the output voltages in the range 75 to 105% of
V
source.
For double-output models, the output voltage is sensed by a
separate transformer winding close to the secondary and fed

back to the primary control circuit. Close magnetic coupling is
provided by the planar construction, ensuring very good
regulation, and allowing for flexible load distribution. The Trim
input of double-output models is referenced to the primary
side, and allows for programming the output voltages in the
range of 100 to 105% of V
resistor, or within 75 to 100% of V
voltage source.
Current limitation is provided by the primary circuit, thus
limiting the total output current (I
sum I
The inhibit input i allows remote control of the outputs; pin i
must be connected to Vi– to activate the converter.
