MAX16821

大功率、同步整流HB LED驱动器,可快速响应脉冲电流

MAX16821A/MAX16821B/MAX16821C脉宽调制(PWM) LED驱动控制器以紧凑的封装和最少的外部器件提供高输出电流能力。MAX16821A/MAX16821B/MAX16821C适用于同步和非同步降压(buck)、boost、buck-boost、SEPIC和Cuk LED驱动器。一路逻辑输入(MODE)允许器件在同步buck和boost工作模式间转换。该器件是第一个专门为满足共阳极HB LED而设计的高功率驱动器。\n IC提供平均电流模式控制,允许使用具有最佳电荷和导通电阻指标的MOSFET,甚至在提供30A LED电流时,也可使对外部散热需求减至最低。\n 差分检测 \n• 真差分远程输出检测 \n• 4.75V至5.5V或7V至28V输入电压范围 \n• 过热关断 \n• 低端buck模式,具有或没有同步整流 \n• 125kHz至1.5MHz可编程/可同步开关频率 \n• 为下一级驱动提供180°错相时钟输出 \n• -40°C至+125°C工作温度范围;
