文章详细介绍了基于TRUEC2(True Constant Current的缩写)技术非隔离BUCK拓扑,来实现极高精度LED恒流控制。试验证明,全闭环TRUEC2技术实时检测真实输出电流,免受输入电压、外部电感影响,突破性地提高了LED输出电流的精度。集成MOSFET,简化外围线路;控制方式免受电感影响,可选择更低价的工字型电感,提高可靠性的同时降低了成本,受到市场广泛欢迎。
The article details the non-isolated BUCK topology based on TRUEC2 (True Constant Current abbreviation) technology for extremely accurate LED constant current control. The test proves that TRUEC2 fully closed loop real-time detection of real output current from the input voltage, the impact of external inductance, a breakthrough to improve the accuracy of the LED output current. Integrated MOSFET simplifies peripheral circuits; control mode from the inductance, the choice of lower-cost I-type inductor, improve reliability while reducing costs, by the market is widely welcomed.
