UBA3070 is a high-voltage LED control IC launched by NXP. It is specially designed for applications where large numbers of LEDs have to be driven accurately and efficiently. It is the perfect choice for LCD backlighting systems.
The UBA3070 is an integrated switch‑mode buck converter designed to drive LED strings up to 600 V. It offers direct PWM dimming, fast transient response, zero‑current and zero‑voltage switching, and comprehensive over‑current, over‑temperature, and under‑voltage protection. The device is available in DIP8 and SO8 packages, providing a low‑cost, low‑component‑count solution for high‑voltage LCD backlighting.
Typical applications include high‑voltage backlighting in LCD TVs and monitors, with flexibility for various LED types and screen sizes. The datasheet includes a basic application diagram and pin configuration for both package types, helping designers integrate the driver into their systems.
