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.

Solutions for high-power, long-life CFL/TL applications
UBA2021
The UBA2021 is a 600 V lamp controller and half-bridge driver
IC for high-power, long-life CFL/TL applications. It delivers
constant light output and improves safety with over-power
protection. It contains a driver circuit for an external half-bridge,
an oscillator, and a control circuit for starting, preheating,
ignition, lamp burning, and protection. It is available in a demo
board for 230 VAC and is supported by a calculation tool.
Highlights
} Adjustable preheat ignition time
} Adjustable preheat current
} Adjustable lamp power
} Lamp power independent from mains voltage variations
} Overpower protection
} Lamp temperature stress protection at higher mains voltages
} Capacitive mode protection
} Protection against a drive voltage that is too low for the power
