Product introduction:

The FT8493xx is a high-performance PWM controller for isolated flybacks, the chip operates in CCM mode, the operating frequency decreases as the load decreases, and it has higher efficiency, faster transient response, and lower standby power consumption. At the same time, the use of internal jitter technology can better handle EMI. The integrated high-voltage start-up simplifies the peripheral circuitry to meet the six-level energy consumption requirements.

Product characteristics:

l  High integration, high cost performance

l  Integrated high-voltage start-up eliminates the need for start-up resistors

l  Integrated high-voltage and self-powered power eliminates the need for auxiliary windings and VDD diodes and a wide output voltage range

l  Integrated RCS resistor

l  Integrated 750V power switch

l  Low power consumption and high efficiency, meeting the six levels of energy consumption

l  Standby power< 75mW

l  Constant power control

l  Built-in jitter to improve EMI performance

l  Cycle-by-cycle peak current limit, VCC overvoltage/undervoltage protection, overtemperature protection, open-loop protection, output short-circuit protection.
