FT8493xx
The FT8493XX is a high-performance PWM controller for isolated flyback applications. The chip operates in CCM mode, and its operating frequency decreases as the load decreases, resulting in higher efficiency, faster transient response, and lower standby power consumption. Simultaneously, the internal frequency dithering technology better handles EMI. The integrated high-voltage startup simplifies the peripheral circuitry and meets the requirements of Level VI energy efficiency.

Product Introduction:
The FT8493XX is a high-performance PWM controller for isolated flyback applications. The chip operates in CCM mode, and its operating frequency decreases as the load decreases, resulting in higher efficiency, faster transient response, and lower standby power consumption. Simultaneously, the use of internal frequency dithering technology better handles EMI. It integrates high-voltage startup, simplifying the peripheral circuit and meeting Level VI energy efficiency requirements.
