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.
This converter is manufactured in a
state-of-the-art automated manufacturing
facility on a short-cycle-time robotic line
having a capacity of one module every ten
seconds. In-line process controls are
designed to achieve low defect rates and
consistent quality. A comprehensive CIM
system controls the dispatching, assembly
and testing of each module, enabling small
lots to be manufactured as efficiently as
hundreds-of-thousands of units.

... The module may be disabled by pulling PC below 2.3V with respect to the –Input. This may be done with an open collector transistor, relay, or optocoupler. Multiple converters may be disabled with a single transistor or relay either directly or via “OR’ing” diodes. See Figure 1. Primary Auxiliary Supply At 5.7V, PC can source up to 1.5mA.

Hence, available output power is reduced by the same percentage that output voltage is trimmed down. Do not exceed maximum rated output current. 2. The trim down resistor must be connected to the –Sense pin. ...
