This driver is made to operate with Å 48 V or floating power supplies and provides output pulses of either positive or negative polarities or even floating pulses. It can also deliver output pulses featuring two different levels of amplitude. The voltage driver is based on a DC/DC converter operating at a high frequency clock (100 KHz). A master oscillator provides the driver with two complementary clocks with non-overlapping active levels. These complementary clocks are fed to transistors TS1 and TS2 via two open collector drivers, whereby transistors TS1 and TS2 are alternatively brought to non-conduction. A 100 KHz wave is generated which is DC converted by D1-D2 and fed to the RLoad.
