    • Valley Turn-on to Achieve Low Switching Losses
    • Frequency Reduce in Light Load
    • Internal High Current MOSFET Driver: 70Ma Sourcing and 400mA Sinking
    • MOSFET Over-Current Protection (OCP)
    • Internal THD Optimization to Achieve Low THD
    • Internal Transition Optimization
    • Compact Package: SOT23-6

    The SY22824B is a constant voltage Transition-Mode boost controller with Power Factor Correction (PFC) function. Constant ON Time control is applied to achieve high PF and low THD without multiplier. It drives the Boost converter in the Quasi-Resonant mode for high efficiency and better EMI performance. It adopts special design to achieve quick start up and reliable protection for safety requirement.
