What is car charger?
The car charger refers to a car charger that is conventionally powered by a car battery (car 12V, truck 24V), and is widely used in the charging of lithium batteries for 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), but also take into account the harsh environment of the car battery (transient spike voltage, System switching noise interference, EMI, etc.); therefore, the power management IC selected by the car charging solution must simultaneously satisfy: a switching power supply chip that is resistant to high voltage, high efficiency, high reliability, and low frequency (facilitating EMI).
