Brand car charger performance advantages

Advantages:

(1) Due to built-in over-current protection, over-temperature protection and other safety measures of the 2576, combined with the 358 (double op amp) to achieve output constant voltage CV, constant current CC, over-voltage protection OVP and other functions; to achieve a reliable, safe, and perfect Lithium battery charging scheme

(2) The constant current CC and overvoltage protection OVP are realized by controlling the output of the 358 to the 2576 EN, so the charging current has a relatively large ripple, and the response speeds of the CC and OVP are not fast enough (whether by switching 2576 is Work to achieve)

(3) Because the 2576 is a fixed 52K PWM converter, the EMI design of the car charger is relatively easy

(4) Because the 2576 and 358 are all manufactured with 40V high voltage bipolar process, they are more "dirty"

(5) This scheme is commonly used in car chargers of around 0.8A ~ 1.5A;

(6) Fully integrated solution dedicated to vehicle charging, low system cost and high reliability

(7) IC internal CV, CC, OVP are all controlled by PWM; therefore, the output voltage, output current, and output overvoltage protection are more precise and the response speed is fast.

(8) Core Dragon provides a series of cost-effective products with charging current between 0A and 3A.

(9) Appearance advantage, compact, mini, easy to carry, all called mini brand car charger
