UCC28516DW

The UCC28516DW is a power factor correction (PFC) controller from Texas Instruments that enables superior performance in single-stage, form-factor PFC applications. It is designed for applications that require control over the power delivered to a load over a wide input voltage range. It also offers ease of use, flexibility, high performance and efficiency.

The UCC28516DW uses a novel active power factor correction technique that is adaptive to the input line voltage. This technique uses a loop-gain feedback control structure in order to achieve fast transient response and high power factor accuracy across a wide range of line conditions. This technique also offers superior performance by keeping the output voltage ripple within a tight tolerance and reducing power dissipation in the system. The UCC28516DW also features true continuous current mode control that maintains a constant peak current regardless of the input line conditions or load. This allows the system to maintain high efficiency even when operating at light or surge load conditions.

The UCC28516DW provides rich protection and monitoring features. It has integrated digital control with programmable current limit, cycle-by-cycle current limit, and open loop protection. It also has an integrated current sensor that can detect excessive current in the system and provide over-temperature protection by shutting down the IC if the temperature threshold is exceeded. It also has a precision voltage regulator that maintains a constant reference voltage over the full temperature range.

The UCC28516DW is suitable for a variety of applications. It is designed for AC-DC applications such as standby circuits and uninterrupted power supplies, as well as higher power applications such as servers, power supplies, and motor drives. It is also suitable for green energy applications such as solar and fuel cell power supplies. It is also suitable for applications that require wide input voltage range support and high efficiency such as automotive electronics and telecom systems.

In conclusion, the UCC28516DW is an efficient and powerful PFC controller from Texas Instruments that offers a wide range of features and benefits. It provides excellent transient response, power factor accuracy, and high efficiency for a wide range of applications.
