QFN5*5*20Summary:
CX8576 is a step-down DC-DC converter with an input withstand voltage of 30V and the ability to achieve precise constant voltage and dual constant current.
CX8576 is equipped with 10m Ω High side N MOS and 10m 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 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 is a constant voltage, constant current, and step-down DC-DC converter with minimal application, excellent performance, and stable reliability.
