Car charger in the car at the same time, but also for home use, to achieve car charging, direct charging, USB charging three-in-one multifunctional use.
Car fast charger is routinely used for car battery (car 12V, truck 24V) power supply car charger, a large number of portable, handheld devices used in the field of lithium battery charging, such as: cell phones, PDA, GPS, etc.; car charger to consider both the actual needs of lithium battery charging (constant voltage CV, constant current CC, over-voltage protection OVP), but also to 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 for the car charger program must meet both: high-voltage, high efficiency, high reliability, low frequency (conducive to the design of EMI) switching power supply chip; in layman's terms, the requirement is "skinny".
1. Cigarette lighter
In the car cigarette lighter, insert the USB plug, through the standard USB excuse output DC voltage.
2. Check
Check that the electronic product current, point voltage and other electronic design parameters are in full compliance with product specifications.
