Introduction to UCC27200ADRCT

UCC27200ADRCT is a current-mode PWM controller designed for low-side gate driver applications. This product is designed to provide up to 3.4A of peak gate drive current with a wide DC supply range of 8-20V. It also features a low-noise frequency-compensated architecture that reduces or eliminates the need for external compensation components. The output of the control voltage is adjustable from 10V to 15V to further customize the performance of the driver.

Application of UCC27200ADRCT

UCC27200ADRCT is mainly intended for applications such as high current gate driver circuits, including switching power supplies, motor control, battery charging, and other power electronic applications.It is an excellent choice for motor control applications where a low-noise gate driver is necessary to reduce transient current spikes that can cause EMI issues. In addition, its design allows for a high maximum peak current output along with a wide adjustment range of the output voltage and fast transient response.

Working Principle of UCC27200ADRCT

UCC27200ADRCT comprises of two stages: a voltage control oscillator (VCO) and an output stage. The VCO produces a triangle waveform whose frequency and amplitude can be adjusted with an external capacitor and resistor. The VCO adjusts the duty cycle of the output signal based on an input voltage. The output stage is composed of two drivers to generate the required high side and low side gate drive signals. The gate drive signal width is determined by the duty cycle of the triangle wave, which is directly proportional to the compiler voltage. Additionally, the UCC27200ADRCT has added features such as soft start, overcurrent and overvoltage protection, an adjustable current limit, and thermal shutdown.

Conclusion

UCC27200ADRCT is an easy to use gate driver solution for driving high current loads. It is suitable for low noise and fast transient response applications with a wide range of current and voltage inputs. It offers adjustable overcurrent protection, adjustable frequency, and adjustable output voltage for higher efficiency and safety. Furthermore, UCC27200ADRCT features integrated features such as soft start and thermal shutdown for protection in fault conditions. Overall, UCC27200ADRCT is an ideal choice for driving IGBTs, MOSFETs and other high current loads in motor control, switching power supply, and battery charging applications.
