... LARGE PIEZO ELEMENTS • OFF-LINE DRIVERS • C-D WELD CONTROLLER DESCRIPTION The SA03 is a pulse width amplifier that can supply 3000W to the load. An internal 45kHz oscillator requires no external components. The clock input stage divides the oscillator fre- quency by two, which provides the basic switching of 22.5 kHz. ...

... Guaranteed but not tested 100% duty cycle is not required V The SA03 is constructed from MOSFET transistors. ESD handling procedures must be observed. CAUTION The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes. ...

... ON condition. This means, in turn, that if the input 1K SHUTDOWN signal to the SA03 at startup is demanding a 100% duty cycle, SIGNAL the output may not follow the command and may tri- R state condition. The ramp signal must cross the input signal SHDN at some point to correctly determine the output state ...
