Free supply of high current DCDC buck chip CX8871 samples, CX8871 specifications and technical support!

Do you have a high current DCDC buck chip with a 20V input and a 12V/6A output?

Of course, it is CX8871 or CX8571 (with an external dual N MOS, the amount of current that can be made depends on the supporting MOS power. Our company can provide high current dcdc buck chips CX8571/CX8871 with supporting MOS, which are sold directly from the original factory and have a higher cost-effectiveness solution for high current car charging chips)

Choose CX8571 or CX8871? What is the difference between CX8571 and CX8871? Salespeople usually make corresponding recommendations based on the functional requirements of customer solutions!

The difference between CX8571 and CX8871:

CX8571 requires frequency compensation, the COMP/EN pin cannot be suspended, and the switching frequency of 120KHz cannot be adjusted. The LX pin string requires a 4.7R resistor to be connected to the inductor, and the BS pin string requires a 100NF capacitor to be connected to the inductor.

However, CX8871 does not require frequency compensation, and the COMP/EN pin can be suspended. The switching frequency after suspension is 110KHz, and the external resistance to ground can adjust the switching frequency. The resistance cannot be less than 200K. LX pin does not require a series resistor,BS pin string 100NF capacitor and 4.7R-10R resistor to switch LX switch pin, VIN pin power supply does not require string resistor and bypass capacitor.
