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 o nom , using either an external resistor or an external voltage
source.
For double-output models, the output voltage is sensed by a

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 o nom by means of an external
resistor, or within 75 to 100% of V o nom , using an external
voltage source.

Current limitation is provided by the primary circuit, thus
limiting the total output current ( I o nom for the single- and the
sum I o1 nom + I o2 nom for double-output models).
The inhibit input i allows remote control of the outputs; pin i
must be connected to Vi – to activate the converter.
