Recommended 4.8A high current built-in MOS car charging solution, providing CX8576 specifications, CX8576 samples, and technical support!

4.8A car charging chip solution, recommended for high current special materials in car charging factories is CX8576. The periphery is quite simple, only 1 inductance+2 capacitors are required on the front, and a small amount of capacitance and resistance are required on the back. In addition to a built-in MOS, the main control chip CX8576 is packaged in QFN20L5 * 5

CX8576 Specification Overview:

CX8576-N is a step-down DC-DC converter with an input withstand voltage of 40V and the ability to achieve precise constant voltage and dual constant current.

CX8576-N has a built-in 15m Ω High side N MOS and 12m Ω Low side NMOS, which can support 4.8A continuous output current and adjustable output voltage, with a maximum support of 95% duty cycle.

CX8576-N achieves external shutdown function by lowering the logic level of the COMP/EN pin and entering standby mode. External compensation enables the feedback control loop to have good line voltage adjustment rate and load adjustment rate, and the peripheral design is flexible.

CX8576-N is a stable and reliable constant voltage and constant current buck DC-DC converter with minimal application, excellent performance, and reliability
