DESCRIPTION
The 724 converts a single 5VDC to 16VDC input into
four pairs of bipolar output voltages of approximately
half the output voltage. The converter is capable of
providing a total output current of 128mA at rated
voltage accuracy and up to 500mA without damage.
The four 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 paral-
lel for higher output current as a single channel iso-
lated DC/DC converter.
Integrated circuit construction of the 724 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, and low leakage coating used on the internal
assembly.
A self-contained 800kHz oscillator drives switching
circuitry, which is designed to eliminate the common
problem of input current spiking due to transformer
saturation or crossover switching.
