  • Product Introduction

The LT3598 features 6 strings of 30mA LED drivers with 1.5% current matching accuracy

peculiarity

  • True Color PWMTM 调光提供了高达 3000:1 的调光比
  • 能够以高达 30mA 的电流来驱动 6 串 LED
  • ±1.5% 的 LED 电流匹配准确度
  • 宽输入电压范围：3.2V 至 30V
  • 输出电压高达 44V
  • 即使在 VIN > VOUT 的条件下也能调节电流
  • LED 在停机模式中被断接
  • 可编程开路 LED 保护 (已调)
  • OPENLED  报警引脚
  • 可编程 LED 温度降额
  • 可调频率：200kHz 至 2.5MHz
  • 可同步至一个外部时钟
  • 可通过通道并联来为每个 LED 串提供更高的电流
  • 耐热性能增强型 4mm x 4mm QFN 封装和 24 引线 TSSOP 封装
  • LT®3598 是一款固定频率、升压型 DC/DC 转换器，专为以一个高达 44V 的输出电压来驱动多达 6 串 LED 而设计。LED 调光功能可利用 CTRL 引脚上的模拟调光电路以及 PWM 引脚上的脉宽调制调光电路来实现。LT3598 能够准确地调节 LED 电流，即使在输入电压高于 LED 输出电压的情况下也不例外。开关频率可以利用一个外部电阻器来设置，可调范围为 200kHz 至 2.5MHz。

  • Other features include programmable overvoltage protection, switching frequency synchronization to an external clock, LED current derating based on junction temperature and/or LED temperature, LED string deactivation control, OPENLED alarm pins, and output voltage limiting when all LED strings are disconnected. The LT3598 is available in a thermally enhanced 24-pin (4mm x 4mm) QFN package and a 24-pin TSSOP package
