General Description
The Supertex HV9120 and HV9123 are Switch Mode Power
Supply (SMPS) controller subsystems that can start and run
directly from almost any DC input, from a 12V battery to a rectified
and filtered 240V AC line. They contain all the elements required
to build a single-switch converter except for the switch, magnetic
assembly, output rectifier(s) and filter(s).
A unique input circuit allows the 912x to self-start directly from a
high voltage input, and subsequently take the power to operate
from one of the outputs of the converter it is controlling, allowing
very efficient operation while maintaining input-to-output galvanic
isolation limited in voltage only by the insulation system of the
associated magnetic assembly. A
±
2% internal bandgap refer-
ence, internal operational amplifier, very high speed comparator,
and output buffer allow production of rugged, high performance,
high efficiency power supplies of 50 watts or more, which can still
be over 80% efficient at outputs of 1.0W or less. The wide dynamic
range of the controller system allows designs with extremely wide
line and load variations with much less difficulty and much higher
efficiency than usual. The exceptionally wide input voltage accep-
tance range also allows much better usage of energy stored in
input dropout capacitors than with other PWM ICs. Remote on/off
controls allow either latching or nonlatching remote shutdown.
During shutdown, power required is under 6.0mW.
