    Southchip SC8745D High‑Power Buck‑Boost for 50W Proprietary Wireless Charging Transmitter

    SC8745D is a high‑performance two‑low‑side‑FET buck‑boost controller in FCQFN‑20 package(3×5mm).

     

    - Vin: 3.7V‑36V, Vout:1V‑29V, max current 6.35A, peak power up to 140W


    - Ideal for 50W proprietary wireless fast‑charge transmitter, compatible with Qi BPP/EPP


    - Full I²C programmable: voltage, current limit, switching frequency, spread‑spectrum


    - NTC thermal fold‑back function: reduce power gradually instead of shutdown under high temperature


    - Built‑in spread‑spectrum, greatly reduce EMI risk, simplify CE/FCC certification


    - AEC‑Q100 automotive qualified, works for 12‑24V car wireless charger & desktop wireless station


    - Rich protection: OVP, UVP, OCP, short‑circuit, battery short protection
