Summary:

CX8833 is a constant voltage, constant current, and step-down DC-DC converter with minimal application, excellent performance, and stable reliability.

CX8833 is a step-down DC-DC converter with an input withstand voltage of up to 30V and the ability to achieve precise constant voltage and current.

CX8833 has a built-in 50m Ω High side PMOS and 30m Ω Low side NMOS, which can support 3A continuous output current and adjustable output voltage, with a maximum support of 100% duty cycle.

CX8833 has high-performance load response and input voltage response capabilities, while precise constant voltage and constant current control loops achieve minimal load and linear adjustment rates.

CX8833 does not require external compensation and can rely on its built-in stable loop to achieve constant current and voltage control, while also having cable voltage drop compensation function.
