以下为激光测距仪部分原理框图:
SGM3206典型应用图如下:
圣邦微的负压电荷泵SGM3206应用于激光测距仪有以下优势:
1、输出负压范围为-1.4V到-5.5V的电压给运放,满足多种供电需求,应用场景广泛;
2、静态功耗仅为120μA,自身损耗低,适合电池供电的便携设备设计;
3、集成有源肖特基二极管,减少外部元器件数量,节约PCB板面积
综上所述,圣邦微的负压电荷泵SGM3206转换效率>90%,静态功耗仅120μA,非常适用于激光测距仪。

【经验】国产BUCK-BOOST电源芯片、负电荷泵芯片助力光模块电源管理负压电路方案,外围电路设计简单
光模块电源管理电路中有需要为EML驱动电路供电的负压电路,目前国产有以下两种负压电路方案可供参考。方案一是利用BUCK-BOOST电路来实现,通过电感储能来实现负电压的转换,外围电路设计简单。方案二是采用负电荷泵来实现,通过电容储能来实现负电压的转换,无需使用电感,外围电路简单可靠。
请问有没有国产的正压转负压电源芯片?
推荐国产圣邦微充电棒DC/DC 转换芯片SGM3204、SGM3206、SGM3207、SGM3209,详细电性参数参考如下图示:
【经验】电压反相器SGM3204/SGM3206用于光模块EML,输出电流最高达200mA并满足其小型化需求
光模块中的EML是电吸收调制器(EAM)和DFB激光器组成的集成器件,在该系统中的EAM需要外加方向电压才能正常工作,电流约为50mA左右。而光模块的供电电压是3.3V,所以需要能产生负压的电源芯片。圣邦微推出的电荷泵SGM3204和SGM3206工作电压1.4~5.5V,输出电流分别为60mA和200mA,输出为-Vin,满足光模块中EAM的参数需求。
【应用】圣邦微负压电荷泵SGM3206YN5G/TR用于气体质量流量控制器项目,静态功耗120μA
客户的气体质量流量控制器项目中运放设计使用的是正负5V供电,这就需要一款电荷泵来产生负压输出连接到运放的负压供电端。圣邦微电子的无调节60mA电荷泵电压逆变器SGM3206YN5G/TR,1.4V至5.5V的输入电压直接逆变产生负压,满足-5V输出要求。
【应用】电压逆变器SGM3206在光模块中的应用
光模块的基本工作原理就是一个光电转换的过程,激光器是其中的核心部分,激光器的工作状态,会直接影响到光信号的质量,激光器部分的设计不仅仅需要考虑本身的参数,还与激光器的恒流驱动部分有关。激光器部分设计如下:这种应用在高速光模块中应用非常广泛,比如400G,单波100G等应用,上图构架采用的是大电流运放供电,这个运放需要提供负压-1.8V,本文推荐圣邦微的SGM3206。
