On-board chargers refer to conventional onboard chargers powered by car batteries (12V for cars, 24V for trucks), which are widely used in the field of lithium battery charging for various portable and handheld devices.
Such as mobile phones, PDAs, GPS, etc.; car chargers must not only 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 peak voltage, System switching noise interference, EMI, etc.); therefore, the power management IC selected for the car charger solution must also meet: high-voltage, high-efficiency, high-reliability, and low-frequency (conducive to EMI design) switching power supply chips.
The car charger is generally used for car battery power supply. It has 6 charging methods, such as multi-function, portable, stylish, and safety precautions, and various kinds of portable, hand-held, etc.
