IMX70, IMY70 Series Data Sheet
70 to 90 Watt DC-DC Converters
Functional Description
The IMX/IMY70 Series converters are comprised of a
feedback-controlled forward converter using current-mode
pulse width modulation (PWM). The switching frequency is
fixed; it can by externally synchronized for double-ouput
models. The main transformer and the output choke are
designed in planar technology, which guarantees excellent
mechanical features and reproducibility of electric properties.
No optocouplers are used.
Single-output converters exhibit at the output a synchronous
rectifier and sense lines to ensure accurate output voltage
regulation. An auxiliary input R allows adjustment of the output
voltage. Proper parallel operation is possible using the current
sharing feature.
Double-output converters exhibit Schottky diodes at both
outputs. The first output voltage is sensed and accurately
regulated by influencing the PWM via the magnetic feedback.
The output voltage is transferred to the primary side by
magnetic feedback via a pulse transformer. The 2 nd output is
tracking. The close magnetic coupling of the main transformer
and the main choke guarantee minor deviation of both output
voltages. Both outputs can be simultaneously adjusted by the
R input located on the secondary side.
A current limitation circuits limits the possible output power.
The topology allows for single-output models an unlimited
output capacity and for double-output models a high output
capacity; see Electrical Output Data .
An incorporated protection disables the converter in an
overtemperature condition. The converter automatically
recovers, after the temperature has dropped below the limit.
The input voltage is monitored, shutting down the converter in
an overvoltage condition. The minimum input voltage for start-
up can be externally adjusted, which helps to limit the input
current at low input voltage.
