Product data sheet

1. General description

The UBA2035 is a high voltage monolithic Integrated Circuit (IC) manufactured in a High

Voltage Silicon On Insulator (HVSOI) process. This circuit is designed for driving

MOSFETs 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 UBA2035 is especially suitable for High Intensity Discharge (HID) lamp drivers for

projectors and general lighting applications for which a small non-overlap time is required.

2. Features

I Full bridge driver circuit

I Integrated bootstrap diodes

I 550 V series regulator input to make the internal supply

I 550 V maximum bridge voltage

I Accurate bridge disable function

I Input for start-up delay

I Adjustable oscillator frequency

I Selectable frequency divider

I Predefined bridge position during start-up

I A fixed non-overlap (< 200 ns)

3. Applications

I The UBA2035 can drive (via the power MOSFETs) any kind of load in a full bridge

configuration

I The circuit is especially designed as a commutator controller for high intensity

discharge lamps in projectors and general lighting applications
