General Description
The Supertex HV441 is a monolithic integrated circuit capable
of generating up to a 70V
of 15 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 sinewave and the DC offset voltage
are adjustable.
For detailed circuit and application information, please
refer to application note AN-H35.
