Synchronous Constant-Current Series Boost LED Driver with PWM Brightness Control and Integrated Load Disconnect

Description The FAN5340 is a synchronous constant-current LED driver capable of efficiently delivering up to 500mW to a string of up to four LEDs in series. Optimized for small form-factor applications, the 1.2MHz fixed switching frequency allows the use of chip inductors and capacitors. Feature

LED 驱动器，同步升压，带 PWM 调光接口

FAN5340 是一种同步恒流 LED 驱动器，能够有效地为四个串联的 LED 提供高达 500 mW 的功率。 针对小尺寸应用而优化，1.2MHz的固定开关频率允许使用片状电感和电容。为了安全起见，该器件集成了短路检测以及过压和热关断保护。 此外，如果电池电压很低，会触发输入欠压闭锁保护。亮度（可调光）控制通过EN引脚上施加300Hz至1kHz的PWM信号来实现。 关断期间，FAN5340 将 LED 阳极从保持升压稳压器电压 COUT的升压稳压器输出端上断开，从而减少 PWM 调光的音频噪声，并断开 LED 串的电源。 •同步电流模式升压转换器\n•高达 500 mW 输出功率\n•支持 2、3 或 4 个串联 LED\n•2.7 V 至 4.8 V 输入电压范围\n•1.2 MHz 固定开关频率\n•1 mA 最大静态电流\n•软启动功能\n•输入欠压锁定 (UVLO)\n•输出过压保护 (OVP)\n•短路检测\n•热关断 (TSD) 保护;
