SMFL Series™ 28 volt DC-DC converters are
rated up to 65 watts output power over a -55°C to +125°C
temperature range with a 28 volt nominal input. On dual output
models, up to 70% of the rated output power can be drawn from
either the positive or negative outputs. The welded, hermetically
sealed package is only 3.005 x 1.505 x 0.400 inches.
Isolation between input and output circuits is provided with a
transformer in the forward path and wide bandwidth magnetic
coupling in the feedback control loop. The SMFL Series uses a
unique dual loop feedback technique that controls output current
with an inner feedback loop and output voltage with a cascaded
voltage mode feedback loop.
The additional secondary current mode feedback loop improves
transient response in a manner similar to primary current mode
control and allows for ease of paralleling.
Tight load regulation is achieved through a wide-bandwidth
magnetic feedback circuit.
The SMFL Series converters have two inhibit terminals (Inhibit
1 and Inhibit 2) that can be used to disable power conversion,
resulting in a very low quiescent input current. See Table 5 on
page 6 for specifications.
Converters may be synced to an external clock (525 to 675 kHz)
or to one another by using the sync in or out pins. See Table 5
on page 6 for specifications.
