UBA2025
The UBA2025 is the same as the UBA2021, but with integrated
3 Ω switches. It supports ignition currents up to 1.5 A and
lamp powers up to 25 W. The IC includes a half-bridge power
circuit, an oscillator, and a control circuit for starting, preheating,
ignition, lamp burning, and protection. It provides all the
necessary functions for proper preheat, ignition, and on-state
operation of the lamp. Besides the control function, the IC
provides the level shift and drive for the two internal power
MOSFETs.
