LT3755IMSE 50W 白色汽车 LED 前照灯驱动器的典型应用电路

桂花蒸 发布

LT3755IMSE 50W 白光汽车 LED 前照灯驱动器的典型应用电路。 LT3755 是一款 DC/DC 控制器，设计用作驱动高电流 LED 的恒流源。它通过内部 7.15V 稳压电源驱动低侧外部 N 沟道功率 MOSFET。固定频率、电流模式架构可在较宽的电源和输出电压范围内稳定运行

说明

  • Typical Application Circuit for LT3755IMSE 50W White Automotive LED Headlamp Driver. The LT3755 is a DC/DC controller designed to operate as a constant-current source for driving high current LEDs. It drives a low side external N-channel power MOSFET from an internal regulated 7.15V supply. The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages

主要特色
