Six-String White LED Driver with Active Current Balancing for LCD Panel Applications

General Description The MAX8790A is a high-efficiency driver for white light emitting diodes (LEDs). It is designed for large liquid crystal displays (LCDs) that employ an array of LEDs as the light source. A current-mode step-up controller drives up to six parallel strings of multiple series-con

6串白光LED)驱动器，提供有效电流均衡，适用于LCD面板

MAX8790A是一款高效白光发光二极管(LED)驱动器。该驱动器专为采用LED背光的大规模液晶显示器(LCD)设计。电流模式升压控制器可同时驱动多个LED串联的6串LED。每串LED都连接至恒流源，可实现±1.5%的电流调节精度，确保均匀的LED亮度。MAX8790A工作于4.5V至26V宽输入电压范围，可为LED提供固定的20mA电流或可调的15mA至27mA电流。\n MAX8790A具有两种亮度调整控制模式，适合不同的应用。在直接DPWM模式下，PWM信号可直接接通或断开LED电流。在模拟亮度调整模式下，内置锁相环(PLL)电路首先将PWM信号转换成模拟信号，然后线性控制LED \n• LED串之间的电流调整精度为±1.5% \n• 升压控制器可将输出电压调整到刚好高于LED串所需的最高电压 \n• 可实现100:1的宽范围亮度调整 \n• 内置PLL可用于同步亮度控制 \n• 输出过压保护 \n• 外部MOSFET允许每串具有多个LED \n• 小型、20引脚、4mm x 4mm薄型QFN封装;
