converters developed principally for use as power supplies
to drive variable capacitance diodes. Both products are low
power output types, suitable for operation at low voltages.
To suppress AM band noise, they use high frequency sine
wave oscillation. Both products are available in two output
voltages, allowing the user to select the most efficient
voltage for the equipment. The products have built-in rec-
tifier diodes and small packages, contributing to equipment
miniaturization.

Note 1: Power dissipation must be derated at the rate of 1.6 mW/°C for operation above 25
°C.
Note 2: Use caution when decreasing the output capacitance at low temperatures. "UJ" type capacitors will allow little change in
the oscillation frequency.
