R2A20133DSP#W5

The R2A20133DSP#W5 is a Power Management Integrated Circuit (PMIC) designed primarily for Power Factor Correction (PFC) applications. It works by controlling the power supply to ensure that its input current follows a desired profile, such as sinusoidal, triangular or trapezoidal. This ensures that the power delivered to the load is consistent and efficient, and reduces the amount of harmonics emitted from the system.

The R2A20133DSP#W5 is a 3 Phase, Fully Digital controller for PFCs employing FETs and IGBTs as switches. It incorporates a sophisticated DSP Core with 8 bit micro-controller unit and digital logic functions. This PMIC is capable of providing control for AC-DC PFCs up to 6.6 KVA, and is also suitable for 12V DC/400V AC and 400V DC/400V AC PFC applications.

The working principle of the R2A20133DSP#W5 involves measuring the input voltage, calculating the reference voltage, and then feeding the pulses to the FET/IGBT gate drivers or the gate signals. The gate signals then act as triggers to the respective FET and IGBT switches, which in turn control the power flow so that the PFC performs as intended. Moreover, this PMIC supports local dimming control, which helps to reduce current harmonics and improve efficiency.

This PMIC is mainly designed for use in three phase power factor correction, where efficiency is critical and the emission of harmonics is to be prevented. Its digital core and pulse width modulation (PWM) capabilities make it suitable for use in applications such as lighting systems, inverters, solar harvesting, motor drives and automation.

In conclusion, the R2A20133DSP#W5 is a PMIC designed primarily for PFC applications, and it is optimized for three phase power factor correction. It allows for control of power supply and deliver efficient output with reduced harmonics. The digital core and PWM capabilities of this PMIC make it suitable for various applications, and are especially beneficial in applications where efficiency and emission of harmonics needs to be optimized.
