    SDH8654S has a built-in high-voltage startup constant current source, features low standby power dissipation and multi-mode control. At heavy load condition, it works in PWM mode. At light load condition, it works in PFM mode to improve the conversion efficiency. At no load, it enters burst mode to reduce the standby power dissipation.

    SDH8654S integrates switching frequency jitter to achieve low EMI. Built-in peak current compensation circuit makes the limit output power consistent even with different input AC voltages. Built-in soft startup reduces the transformer stress during power-on process to avoid transformer saturation.

    SDH8654S integrates comprehensive exceptional protections including leading edge blanking (LEB), cycle-by-cycle peak current limit, VCC overvoltage protection(OVP), output overload protection(OLP), AC input undervoltage protection(AC_UVP), AC input overvoltage protection (AC_OVP) and over-temperature protection(OTP) etc.
