CP2158

低噪声的电荷泵型闪光灯驱动芯片

CP2158为一款低噪声的电荷泵型闪光灯驱动芯片，专为大电流高亮度LED闪光灯提供驱动而设计，在3.7V电源电压下CP2158的最大输出功率可达3.5W。支持手电筒模式和闪光灯模式的切换。CP2158内置的电荷泵可以根据负载与电源的状态自动在1倍电荷泵模式和2倍电荷泵模式之间切换，确保为LED输出恒定的电流。\r\n 在手电筒模式下，CP2158默认FB电压为50mV。FLASH模式下的FB电压由外部的RSET电阻进行设置，推荐RSET电阻的选取范围55K至120K，分别对应270mV至125mV的反馈电压。（FB参考电压的计算公式：VFB=（1.23/RSET）X12.1K）\r\n ; -闪光灯峰值输出电流900mA-支持TORCH模式与FLASH模式-TORCH模式下FB电压内置为50mV-FLASH模式下FB电压由外置电阻配置-FLASH模式下内置了280ms的闪光时间限制Ÿ-TORCH模式下最高效率90%Ÿ-具备软启动电路防止对电源产生大电流冲击Ÿ- 关机电流小于1uAŸ-2MHz的开关频率Ÿ-过压保护功能Ÿ-碰地保护功能-过温保护功能Ÿ-3mmX3mm 10-PIN DFN封装\n;
