Half-bridge power IC for CFL lamps

Rev. 6.2 — 1 November 2010

Product data sheet

1. General description

The UBA2024 is a family of high-voltage monolithic Integrated Compact Fluorescent

Lamp (CFL) drivers for a large range of lamp powers. Specific versions are optimized for

230 V and 110 V mains supplies. The product family integrates full CFL controller

functionality with high voltage half-bridge transistors. All products in the UBA2024 family

are pin-to-pin compatible enabling a single application design covering a wide range of

power ratings.

The IC features 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.

2. Features and benefits

„ The common feature set includes:

‹ high power efficiency

‹ a high integration level with low component counts enabling small form factor

electronic ballast

‹ integrated bootstrap diode

‹ soft start function

‹ minimum glow time control

‹ integrated low-voltage supply

‹ adjustable operating frequency as a result of the embedded oscillator

‹ an accurate 50 % duty cycle provided by an embedded oscillator signal

‹ integrated half-bridge power transistors

‹ an internal drive function with a high-voltage level shifter up to 550 V (300 V for the

UBA2024BP and UBA2024BT)

3. Applications

„ Driver for any kind of half-bridge configured load up to 23 W, provided that the

maximum junction temperature is not exceeded

„ Designed for electronically self-ballasted CFL lamps
