The AOZ1948 combines key performance and device safety features for improved solution reliability and robustness. The device's current control method provides a best-in-class LED current regulation of better than 2% and supports duty cycles up to 90%. In addition, the AOZ1948 integrates many fault detection and safety features such as over-current protection, auto-restart OCP, thermal overload, and high voltage sensing and adjustable fault timer.
"I am excited about the market prospect for the AOZ1948, our first step-down LED controller IC for advanced lighting solutions," said Wayne Eng, Director of Product Marketing at AOS. "The buck topology in LED backlighting solutions offers our customers improved overall solution cost with reduced component count and smaller footprint on the PCB."
Pricing and Availability
The AOZ1948 is immediately available in production quantities with a lead-time of 12 weeks. The unit price for 1,000 pieces is $0.495.
