Solutions for standard CFL applications

UBA2024

The UBA2024 is a 550 V lamp controller and half-bridge IC, equipped with 9 Ω switches, that supports standard CFL applications up to 15 W.

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.

Highlights

} Integrated half-bridge power transistors

} Integrated bootstrap diode

} Integrated low-voltage supply

} Adjustable oscillator frequency

} Maximum voltage of 550 V

} Minimum glow time control

} Soft start

} Easy-to-configure burner specification

} Compact DIP8 and SO14 packages

UBA2024A

The UBA2024A is a pin-compatible variant of the UBA2024.

It extends the application rage to include systems up to 21 W. In the DIP8 package, it integrates 6 Ω switches, and in the SO14 package, it has 6.4 Ω 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 delivers a lower Ptot with the same Plamp, higher efficiency, and lower loss.
