SOP-8Summary:
CX8852 is a step-down DC-DC converter with an input withstand voltage of 40V and the ability to achieve precise constant voltage and dual constant current.
CX8852 has a built-in 20 m Ω High side N MOS and 20m Ω Low side MMOS, which can support 4A continuous output current and adjustable output voltage, with a maximum support of 98% duty cycle.
CX8852 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.
CX8852 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.
CX8852 is a constant voltage, constant current, and step-down DC-DC converter with minimal application excellent performance, and stable reliability.
