Product Overview
This DC-DC converter module uses
2nd Generation power processing, control
and packaging technologies to provide the
performance, flexibility and cost effectiveness
expected of a mature power component.
For example, a plated-cavity core transformer
couples widely separated primary and
secondary windings, resulting in low in-to-
out parasitic capacitance and noise.
High frequency ZCS/ZVS switching,
advanced power semiconductor packaging
and thermal management provide high
power density with low temperature
gradients. Extensive use of silicon
integration results in 1/3 the part count
of a 1st Generation converter.

Power chip control
The 494 chip changes the level and sends it to pin 15 (input pin), and then feeds back to pin 3. I found that some circuits add a 1UF capacitor between the two. Doesn't this mean that it cannot be adj...
