IK3051 Overview
IK3051 is a highly integrated solution for SMPS applications requiring constant voltage and constant current mode. IK3051 integrates one voltage reference, two operational amplifiers (with ORed outputs mon collectors), and a current sensing circuit. The voltage reference bined with one operational amplifier makes it an ideal voltage controller, and the other low voltage reference bined with the other.

- 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 volt
- A sense resistor having a value and allowable dissipation power which need to be chosen according to the internal voltage threshold
