Description
These triple output converters are designed for wide input
range telecommunications, medical instrument and industrial
control system applications. The converters have a high
accuracy feedback control circuit and coupled inductor
magnetics. This combination provides linear regulator type
performance with switching topology efficiency. Outstanding
line and load regulation are achieved over the full input range
and under the specified load current range. A logic shutdown
pin is also included to inhibit converter operation as is internal
thermal overload
protection. The outputs and the power
switch are both overvoltage protected.
