SOP-8LOverview
The CX8834B is a CC/CV step-down DC-DC converter that supports an input voltage of DC 5V-30V, a fixed output of 5V/2.4A, and features accurate constant voltage and constant current control with 100% duty cycle capability.
The CX8834B integrates a 70mΩ High-side PMOS and a 30mΩ Low-side NMOS, enabling a continuous output current of 2.4A.
The CX8834B offers excellent load transient response and line regulation. Its precise constant voltage and constant current control loops achieve extremely small load and line regulation.
The CX8834B requires no external compensation. It relies on its internal stable loop for constant current and constant voltage control and features a cable drop compensation function.
The CX8834B is an easy-to-apply, high-performance, stable, and reliable CC/CV step-down DC-DC converter.
