TPS92510 恒流降压转换器

Texas Instruments 适用高亮 LED 的恒流降压转换器

TPS92510 恒流降压转换器Texas Instruments 的 TPS92510 针对以下各种应用进行了专门优化，DC/DC 降压 LED 照明应用（如基于更换 MR-16 的改型 LED）、多 LED 灯串应用（如高棚灯和路灯）以及其他高光照应用（如应急灯和闪光灯）。 推出之初 TPS92510 是市面上第一款集成 FET 的 DC/DC 降压转换器，能够以高达 97% 的效率提供 1.5 A 电流，具有频率用户可配置、PWM LED 电流调制以及热返送等三个直流 LED 照明领域客户要求的关键常用功能。 以前的方案要求外接元件才能达到类似的性能，而且会增加照明应用的尺寸和成本。
