This part of the circuit is the core part of the entire car charger system. It provides the necessary voltage and current for the battery during the charging process. Use A P30 03- AD J to design the circuit as shown in the figure. The voltage dividing resistors RA and RB are used to set Output voltage, CFF capacitor can increase the phase margin of the loop and improve system stability. The recommended value range is 10nF to 33nF.
