CXPU3359 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) modes. CXPU3359 integrates one voltage reference, two operational amplifiers (the outputs are OR’ed together, common collectors), and a current sensing circuit. The voltage reference, together with one operational amplifier, makes it an ideal voltage controller

CXPU3359 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) modes. CXPU3359 integrates one voltage reference, two operational amplifiers (the outputs are OR’ed together, common collectors), and a current sensing circuit. The voltage reference, together with one operational amplifier, makes it an ideal voltage controller. The other low voltage reference, together with another operational amplifier, makes it an ideal current limiter for low side output current sensing. The current threshold is fixed, and precise. The CCXPU3359housed in space-saving SOT23-6L package, is ideal for space sensitive applications such as adapters, cellphone chargers, Digital Camera chargers, and other battery chargers.
