SOP-8Summary:
CX8855 is a step-down DC-DC converter with an input withstand voltage of up to 32V and the ability to achieve precise constant voltage and current.
CX8855 has a built-in 30m Ω High side PMOS and 20m Ω Low side NMOS, which can support continuous output current of 3.4A and adjustable output voltage, with a maximum support of 100% duty cycle.
CX8855 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.
CX8855 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.
CX8855 is a stable and reliable constant voltage and constant current buck DC-DC converter with excellent performance and inter pole application.
