SOP-8Summary:
CX8843 is a step-down DC-DC converter with an input withstand voltage of up to 40V and the ability to achieve precise constant voltage and current.
CX8843 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.
CX8843 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.
CX8843 does not require external compensation and can rely on its built-in stable loop to achieve constant current and constant voltage control. It also has cable voltage drop compensation function.
CX8843 is a stable and reliable constant voltage and constant current buck DC-DC converter with excellent performance and application between poles.
