About

About battery chargers

Infineon can support you in your quest to charge just about anything with our comprehensive portfolio that contains dedicated battery charging ICs, a competitive and granular MOSFET portfolio, and power controllers designed to meet customer requirements and needs for battery chargers. For the shortest time to market, Infineon offers ready-to-use lithium-ion battery charger reference designs, including digital design software.

Possible battery-powered applications covered

Just about anything can become battery-powered these days. This is a positive trend that Infineon fully supports in order to decarbonize our planet. One of the many ways we can contribute is to offer battery charging solutions for a wide variety of battery-powered applications, including light electric vehicles such as e-bikes, e-scooters and micro EVs, cordless power tools, and home appliances. On top of battery charging, we also offer comprehensive system solutions for these applications.

Infineon portfolio for battery chargers

Infineon maintains a wide portfolio of available power MOSFETs and controllers that are perfect for your next battery charging design. 

Our OptiMOS™ and StrongIRFET™ silicon power MOSFET families offer a huge selection of options for load switches and SR FETs. Meanwhile, our CoolMOS™ superjunction MOSFETs in SOT-223, TO-220, or TO-252 DPAK packages are the perfect choice for PFC/PWM HV FETs with an excellent price/performance ratio. Further, our catalog of PFC/PWM controllers will keep you smiling with their flexibility and features. Choose from our XDP™ family of digital power hybrid flyback controllers that combine the traditional flyback topology with the performance of a resonant converter, or even our highly integrated XDPS2221 which combines PFC boost and hybrid flyback conversion features. Or if you are in the market for something a little more tailored, check out our ICC80QSG, which is a flyback controller that is specifically designed for battery chargers up to 130 W.
