In the DIP8 package, it integrates 6 switches, and in the SO14 package, it has 6.4 switches. It enables a single PCB layout with multiple power levels, and reduces switching losses with a 5-6% improvement in efficiency. When compared to a discrete driver, the UBA2024A UBA2024A delivers a lower Ptot with the same Plamp, higher efficiency, and lower loss. The high level of integration reduces the number of external components to only 17 (compared to the 27 typically required by a discrete driver solution), and the IC supports NXP's patented glow phase. The IC includes a soft-start function, an adjustable internal oscillator and an internal drive function with a high-voltage level shifter for driving the half bridge. To guarantee an accurate 50% duty cycle, the oscillator signal is passed through a divider before being fed to the output drivers. It is available in a demo board for 120 and 230 VAC and is supplied with a calculation tool that lets the engineer fine-tune the board to a given burner specification.
