General Description
The Supertex HV9120 is a Switch Mode Power Supply
(SMPS) controller subsystem that can start and run
directly from almost any DC input, from a 12V battery to
a rectified and filtered 240V AC line. It contains 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 9120 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 reference, internal operational
amplifier, very high speed comparator, and output buffer
allow production of rugged, high performance, high efficiency
power supplies of 50W 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
range also allows 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, the power required is under 6.0mW.
For detailed circuit and application information, please
refer to application notes AN-H13 and AN-H21 to AN-
H24.

... DD sistor between the OSC IN and OSC OUT pins is required to set oscillator frequency (see graph). One difference exists between the Supertex HV9120 and competitive 9120s: The oscillator is shut off when a shutoff command is received. This saves about 150µA of quiescent current, which aids in the construction of power supplies to meet CCITT specifi ...
