SOP-8Summary:
CX8830 is a step-down DC-DC converter with an input withstand voltage of up to 30V and the ability to achieve precise constant voltage and current.
CX8830 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.
CX8830 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.
CX8830 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.
CX8830 is a stable and reliable constant voltage and step-down DC-DC converter with excellent performance and inter pole application.
CX8830 has built-in FCP/QC2.0/3.0/BC1.2/YD/T 1591-2009/USB DCP D+2.7V D-2.7V/USB DCP D+1.2V D-1.2V various fast charging protocols.
