UBA2024BT/N1,518

Lighting, Ballast Controllers Overview

The UBA2024BT/N1,518 is a high-voltage monolithic integrated Compact Fluorescent Lamp (CFL) driver from the UBA2024 family. It integrates full CFL controller functionality with high-voltage half-bridge transistors optimized for 110 V mains supplies. The device operates at an adjustable frequency between 40.05 kHz and 42.68 kHz, with a supply voltage range of 11.4 V to 13.3 V. It features a maximum output current of 1.2 A and operates within a temperature range of -40°C to 150°C in a 14-SOIC package.

Lighting, Ballast Controllers Feature Summary

• Integrates high-voltage half-bridge power transistors with an internal drive function and level shifter up to 300 V.
• Includes soft start function and minimum glow time control for reliable lamp operation.
• Features an adjustable internal oscillator providing accurate 50% duty cycle via signal division.
• High integration level reduces external component count, enabling small form factor electronic ballasts.

Lighting, Ballast Controllers Applications

• Driver for electronically self-ballasted CFL lamps
• Half-bridge configured load drivers up to 23 W
• Compact fluorescent lighting systems optimized for 110 V mains

Lighting, Ballast Controllers Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm RoHS compliance status and REACH registration details prior to integration. Check for End-of-Life (EOL) notifications as the product may be discontinued. Ensure storage conditions meet moisture sensitivity level requirements to prevent damage during assembly.

Lighting, Ballast Controllers Selection Notes

Select this variant specifically for 110 V mains applications due to its optimized internal specifications. Compare against UBA2024BP for different voltage ratings if 230 V support is required. Ensure the design accommodates the 14-SOIC package dimensions and thermal dissipation needs for junction temperatures up to 150°C.

Lighting, Ballast Controllers Part Context

Part of the UBA2024 family of high-voltage monolithic CFL drivers. All products in this family are pin-to-pin compatible, allowing a single application design to cover a wide range of power ratings. The series integrates controller functions with power transistors for compact electronic ballast designs.
