Features

General Description

❏

220V maximum operating voltage

Integrated high voltage transistors

Up to 70 V_RMSring signal

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,

theTN2524N8andoneP-ChannelMOSFET, theTP2522N8.The

high voltage outputs have pulse by pulse over current protection

set by two external sense resistors.

Adjustable AC and DC output voltage level

Adjustable ring signal start phase angle

Pulse by pulse output over current protection

5 REN output capability

TheHV441generatesalowvoltagereferencesinewavebyusing

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.

External MOSFETs enhance output rating to 20 REN
