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