Intelligent LED lighting power drive solution based on TI products

As we all know, an excellent LED intelligent lighting driver solution must have an excellent power driver. Based on the current hot LED market , broad prospects and rich profits, Youshang launched an LED lighting driver solution based on TI TPS92314 products, which has won the favor of more and more designers with its high integration, high efficiency and high reliability.

　　Solution Features:

　　1. Regulate LED current without secondary side induction;

　　2. Critical conduction mode (CCM) (with zero current detection for valley switching);

　　3. Adaptive on-time control with intrinsic PFC;

　　4. Programmable switch-on delay;

　　5. Overheat protection.

　　TI TPS92314 Introduction:

　　The TPS92314 is an offline primary-side inductive converter with PFC, more specifically, an isolated primary-side controlled critical conduction mode PFC flyback. The controller operates in critical conduction mode with valley switching and has very few external components, making the design easier.
