IK3051 General Description
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 common collectors), and a current sensing circuit. The voltage reference combined with one operational amplifier makes it an ideal voltage controller, and the other low voltage reference combined with the other operational amplifier makes it an ideal current limiter for output low side current sensing. The current threshold is fixed and precise. 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.
• Optional compensation components (R and C). IK3051, is ideal for smallest package available, is ideal for space shrinked applications such as adapters and battery chargers.
