DESCRIPTION
The HL02U Series offers an extensive selection of input
and output voltages to choose from. These miniature,
unregulated DC/DC converters come in 24-pin DIP and
SMD packages. This small size is possible through the use
of surface mount manufacturing technologies.
The HL02U Series utilizes a 110KHz push-pull oscillator
in the input stage with internal filtering to reduce the
output noise while maintaining good efficiency.
The use of surface mount construction and automated
manufacturing processes increase consistency and reli-
ability while reducing overall cost.

YPICAL PERFORMANCE CURVES
NOTES:
1.) When operated within the SAFE OPERATING AREA as defined
by the above curves, the output voltage of HL02U devices is
guaranteed to be within 95% of its steady-state value within 100
milliseconds after the input voltage has reached 95% of its steady-
state value.
2.) For dual output models, total load capacitance is the sum of the
capacitances on the plus and minus outputs.
