Functional Description

Vo1+

The IMX7/IMS7 Series DC-DC converters are feedback-

controlled flyback converters using current mode PWM (Pulse

Width Modulation).

Trim (R)

Vo2+

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

PWM

_{o nom}, using either an external resistor or an external voltage

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_{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).

n.c.

The inhibit input i allows remote control of the outputs; pin i

must be connected to Vi– to activate the converter.
