Car charger

Car chargers conventionally used for car battery (car 12V, truck 24V) power supply are widely used in the field of lithium battery charging of various portable and handheld devices, such as: mobile phones, PDA, GPS, etc .; car chargers must consider lithium The actual needs of battery charging (constant voltage CV, constant current CC, over-voltage protection OVP), and the harsh environment of the vehicle battery (transient spike voltage, system switching noise interference, EMI, etc.) must be taken into account;Therefore, the power management IC selected for the car charger solution must simultaneously meet: high voltage resistance, high efficiency, high reliability, low frequency (conducive to EMI design) switching power supply chips; in general, it requires "skinny."
