The car charger is a car charger that is used to charge digital products anytime and anywhere with the vehicle power supply. It is commonly used in car chargers for car batteries (car 12V, truck 24V). It is widely used in the charging of lithium batteries in various portable and handheld devices, such as: mobile phones, PDAs, GPS, etc.; car chargers must consider the actual needs of lithium battery charging (constant voltage CV, constant current CC, overvoltage protection OVP) It is also necessary to take into account the harsh environment of the vehicle battery (transient spike voltage, system switching noise interference, EMI, etc.); therefore, the power management IC selected by the vehicle charging scheme must simultaneously satisfy: high voltage resistance, high efficiency, high reliability, low frequency ( Switching power supply chip for EMI design)..Any special requirements, we can do custom product for our customers.
