Sketch
The BP87640 is a high-performance quasi-resonant flybackcontroller that can enable zero no-load consumption inrapid charger applications.The BP87640 communicates with the secondary sidecontroller BP62640 via the magnetic coupler BP818 forsecondary-side regulation. Since the magnetic coupleroperates without bias current, the no-load consumption ofthe system is significantly reduced to less than 5 mW. ltnormally operates in QR and DCM mode with valleyswitching for high efficiency and good EMl performance.
Advantage

    Zero no-load consumption (<5 mW)

    Integrated GaN gate driver

    Quasi-resonant operation improves efficiency

    Integrated high-voltage startup circuit

    Up to 150Vauxiliarysupplyforwide range output

    Max switching frequency up to 130 kHz

Application area
  • QC/USB PD/Programable Ac/Dc chargers
