Dual Full Function White LED Driver with Integrated Schottky Diodes

DESCRIPTION The LT®3497 is a dual full function step-up DC/DC converter specifi cally designed to drive up to 12 white LEDs (6 white LEDs in series per converter) from a Li-Ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the

具有集成肖特基二极管的双通道全功能白光 LED 驱动器

LT®3497 是一款双通道全功能升压型 DC/DC 转换器，专为依靠单节锂离子电池来驱动多达 12 个白光 LED (每个转换器驱动 6 个串联的白光 LED) 而特别设计。采用 LED 串联可提供相等的 LED 电流，从而获得均匀的显示亮度，并免除了增设镇流电阻器和进行昂贵工厂校准的需要。\n\n 两个独立的转换器能够驱动不对称的 LED 灯串。另外，准确的 LED 调光和两个 LED 灯串的关断也可独立地控制。LT3497 采用了一种独特的高端 LED 电流检测，从而使该器件能够起一个“单线式电流源”的作用；LED 灯串的一端可在任何位置回接至地，从而实现一种较为简单的单线式 • 可从一个 3V 电源来驱动多达 12 个白光 LED (每个转换器驱动 6 个串联的白光 LED)\n\n• 两个独立的升压型转换器能够驱动不对称的 LED 灯串\n\n• 两个 LED 灯串的独立调光和停机控制\n\n• 高端检测实现了每个转换器的“单线式电流源”\n\n• 内部肖特基二极管\n\n• 开路 LED 保护 (32V)\n\n• 2.3MHz 开关频率\n\n• ±5% 基准准确度\n\n• VIN 范围：2.5V 至 10V\n\n• 双通道 250:1 的宽 True Color PWM™ 调光\n\n• 每个转换器只需要 1µF 的输出电容器\n\n• 采用 ;
