The ICC80QSG is a PWM controller for flyback topologies operating in quasi-resonant mode and valley switching DCM, to achieve high efficiency of power transfer across wide operating range. For battery charging applications, the IC offers a wide power range as well as a comprehensive set of protections. The IC is easy to design in and requires a minimum number of external components. The gate driver current enables reasonable designs up to 130W with state-of-the-art MOSFETs. The system performance and efficiency can be optimized using Infineon CoolMOS™ P7 power MOSFETs.The integrated burst mode function allows designs with a very low standby power consumption during standby mode and very light loads.
