| 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. |
