Texas Instruments 高棚 LED 照明解决方案图片Texas Instruments UCC28810 是一款照明电源控制器，用于要求功率因数校正和符合 EMC 规范的中低功率照明应用。其设计用于控制在临界导通模式下工作的反激式、降压或升压转换器。UCC28810EVM-003 是一款具有功率因数校正功能的 110W 离线式 AC 至 DC LED 电流驱动器。该设计采用三级方法：通用输入升压 PFC 级、提供受控电流源的低压侧降压级、为四个 LED 灯串提供隔离的半桥 DC 变压器级。

TPS92020 是一款高性能谐振开关 LED 驱动器控制器。该器件专用于更高功率的 LED 照明系统中。TPS92020 在 LLC 拓扑结构中采用谐振开关，相比传统的半桥转换器可实现极高的能效。可编程空载时间实现极小励磁电流的零电压开关，从而在各种不同的应用中最大限度提高系统能效。

Texas Instruments LM3409HV 是用于降压电流稳压器的 P 沟道 MosFET (PFET) 控制器。该器件具有宽输入电压范围、高压侧差分电流感应和低可调阈值电压、快速输出启用/停用功能以及热增强型 eMSOP-10 封装。这些特性组合在一起，使 LM3409HV 非常适合用作恒流源来驱动 LED，并可轻松实现高达 5 A 的正向电流。
