SOP-8LOverview
The CX8833B is a buck DC-DC converter capable of withstanding input voltages up to 30V while delivering precise constant voltage and constant current regulation.
The CX8833B integrates a 60mΩ high-side PMOS and a 40mΩ low-side NMOS, supporting a continuous output current of 3.1A.
It delivers high-performance load and input voltage response, while its precise constant voltage and constant current control loops achieve minimal load regulation and line regulation.
The CX8833B requires no external compensation, relying on its internal stable loop for constant current and voltage control, while also featuring cable voltage drop compensation.
The CX8833B is an extremely simple-to-implement, high-performance, stable, and reliable constant voltage/constant current step-down DC-DC converter.
