MAX8521 | 尺寸最小的TEC电源驱动器,用于光模块 MAX8520/MAX8521设计用于驱动空间受限的光纤模块中的热电制冷器(TEC)。这两款器件提供±1.5A输出电流,并控制TEC电流,以消除有害的电流浪涌。片内FET减少了外部元件的数目,高开关频率减小了外部元件的尺寸。\n\n MAX8520/MAX8521工作于单电源,在两个同步buck转换器输出之间连接TEC。这种工作方式允许在低电流时实现无死区和其他非线性的温度控制。这种策略保证在设置点非常接近环境工作点时,控制系统不会发生振荡,仅需少量的加热或者冷却。由模拟控制信号精确地设置TEC电流。\n\n 这两款器件具有精确的、独立可调的加热电流限制和冷却电流限制,以及 • 0.31in²的电路面积\n• 低截面设计\n• 片内功率MOSFET\n• 高效率的开关模式\n• 低噪声的纹波抵消技术\n• 直接电流控制防止TEC电流浪涌\n• 5%精度可调的加热/冷却电流限制\n• 2%精度的TEC电压限制\n• 低输出电流时,无死区或振荡\n• ITEC监测TEC电流\n• 1%精度的电压基准\n• 高达1MHz的开关频率\n• 同步工作(MAX8521); | ADI 亚德诺 | ADI | |
