TPS92070 LED 照明控制器

Texas Instruments 的高能效集成调光 LED 照明控制器

TPS92070 LED 照明控制器Texas Instruments 的 TPS92070 是一款高级 PWM 控制器，适合用于低功耗离线 LED 照明应用。 TPS92070 的集成调光接口电路具有非耗散的调光器触发控制电路。 TPS92070 控制器提供没有光照度波动效应的 DC LED 电流。 DC 电流也会提高 LED 的功效。 TPS92070 根据外部调光器的位置提供指数控制的光输出， 并通过填谷式电路实现高功率因数。 一旦检测到前沿调光器，TPS92070 将设定一个输出以禁用 PFC 电路，从而优化驱动器工作。 LED 电流感应精密误差放大器可实现深度调光。
