Integrated circuit construction of the 722 reduces size
and cost. High isolation breakdown voltages and low
leakage currents are assured by special design and
construction which includes use of a high dielectric
strength, low leakage coating used on the internal
assembly.
A self-contained 900kHz oscillator drives switching
circuitry, which is designed to eliminate the common
problem of input current spiking due to transformer
saturation or crossover switching.

DESCRIPTION
The 722 converts a single 5VDC to 16VDC input into
a pair of bipolar output voltages of the same value as
the input voltage. The converter is capable of provid-
ing a total output current of 64mA at rated voltage
accuracy and up to 200mA without damage.
The two output channels are isolated from the input
and from each other. They may be connected indepen-
dently, in series for higher output voltage or in parallel
for higher output current, as a single channel isolated
DC/DC converter.
