Diodes - Rectifiers - Arrays

The FLLD258TA (Fast Low Loss Diode Array) is a recent diode rectifier array designed for low loss switch control applications. It is based on the highly successful FLLD application-specific integrated circuit (ASIC) range from Taiwan Semiconductor. This type of device is widely used in power supplies, DC-DC converters, and phase-controlled switch controls.

Application Fields

FLLD258TA provides optimized performance for switching control of power applications including switching power supplies, DC-DC converters, rectifiers, and phase control applications. It is particularly suitable for applications requiring a low voltage drop at high-speed switching in the range of 1MHz-5MHz. Additional applications include power supply feedback circuits, snubber circuits, inrush current limitation, motor control, and class-D audio amplifiers.

Working Principle

FLLD258TA is a high speed switching rectifier array with low loss. It works by rectifying the input AC power at high speed to a DC value that can be used by the system. The device contains pairs of diodes that are configured in parallel and oppositely biased, which allows for a rapid conduction when the input voltage exceeds the diode pair’s voltage drop. This helps to reduce the overall power loss in the system. The diodes in the array act together to quickly break the circuit if the input voltage reaches a critical level, allowing the system to protect itself from overvoltage damage.

In addition, FLLD258TA features integrated protection and fault detection circuitry. This added layer of protection ensures that the device operates in a safe and efficient manner, allowing it to be used in a wide variety of demanding applications.

Conclusion

FLLD258TA is an excellent solution for a wide range of applications requiring low loss, fast switching at high speed. The integrated fault detection and protection circuitry helps to ensure reliability and enhanced performance over time. FLLD258TA can be used in power supply applications and in a variety of other applications, including motor control and snubber circuits.
