UBA2024 - NXP

UBA2024 Half-bridge power IC

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 .

Features

„ 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.
