Summary:

CX8834B is a step-down DC-DC converter that supports input DC 5V-30V and output fixed 5V/2.4A, with precise constant voltage and constant current at 100% duty cycle.

The CX8834B is equipped with a 70m Ω High side PMOS and a 30m Ω Low side NMOS, which can support a continuous output current of 2.8A.

The CX8834B has high-performance load response and input voltage response capabilities, while precise constant voltage and constant current control loops achieve minimal load adjustment rate and linearity.

The CX8834B 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 adjustment rate.

CX8834B is a stable and reliable constant voltage and constant current buck DC-DC converter with minimal application, excellent performance, and reliability.
