| Description & Applications | Constant Voltage and Constant Current Controller for Adaptors and Battery Chargers IK3051 is a highly integrated solution for SMPS applications requiring constant voltage and constant current mode. IK3051 integrates one voltage reference, two operational amplifiers and a current sensing circuit. The only external components are: A resistor bridge to be connected to the output of the power supply (adapter, battery charger) to set the voltage regulation by dividing the desired output voltage to match the internal voltage reference value. A sense resistor having a value and allowable dissipation power which need to be chosen according to the internal voltage threshold. |
| 描述与应用 | 恒定电压和恒定电流控制器，适配器和电池充电器 IK3051是一个高度集成的解决方案SMPS需要恒定电压和恒定的应用电流模式。 IK3051集成了一个参考电压，两个运算放大器和一个电流检测电路。唯一的外部组件是： 要连接到的输出的一个电阻桥设置电源（适配器，电池充电器），除以所需的输出电压调节，电压相匹配的内部参考电压值。一个检测电阻值和允许耗散功率，需要根据内部的电压阈值进行选择。 |
