he UBA2037 is a high voltage monolithic integrated circuit manufactured in a HighVoltage Silicon On Insulator process. This circuit is designed for driving MOSFET’s in afull bridge configuration. In addition, it features a disable function, an internal adjustableoscillator and an external clock input function with a high-voltage level shifter for drivingthe bridge. To guarantee an accurate 50 % duty cycle, the oscillator signal can be passedthrough a divider before being fed to the output drivers.The UBA2037 is especially suitable for High Intensity Discharge lamp drivers forprojectors and general lighting applications.
