HV441PJ
General Description
The Supertex HV441 is a monolithic integrated circuit capable of
generating up to a 70V RMS sine wave output at frequencies of
15Hz to 60Hz with a load of 5 North American RENs. Its output
rating can be enhanced to 20 North American RENs with the
addition of two Supertex MOSFETs: one N-Channel MOSFET,
the TN2524N8 and one P-Channel MOSFET, the TP2522N8. The
high voltage outputs have pulse by pulse over current protection
set by two external sense resistors.
The HV441 generates a low voltage reference sine wave by using
external passive components. An external sine wave signal can
be used if desired. The HV441 amplifies the reference sine wave
signal by pulse width modulating the high voltage output at a
nominal frequency of 100KHz. An error amplifier compares the
output sine wave with the reference sine wave and adjusts the
pulse width accordingly. Both the amplitude of the output sine
wave and the DC offset voltage are adjustable.
