UCC39002DGK is a 200V high-voltage current-mode PFC controller with an integrated double-shielded gate driver. It is an integrated power management integrated circuit (PMIC) designed for intelligent power factor correction and active power factor correction systems. It is part of the high-performance microcontroller family designed by Texas Instruments, which offers superior performance and low-power operation.

Unlike traditional linear power factor controllers, UCC39002DGK uses a current-mode approach to PFC regulation that allows it to adjust the power-factor correction level more frequently and accurately. This current-mode control eliminates the need for shunts, inductors, and large external components, making it suitable for high-density and high-efficiency applications. The device’s powerful double-shielded gate driver with its integrated thermal protection, allow for reliable operation and easy system monitoring.

The UCC39002DGK is suitable for a variety of specialised applications including industrial motor control systems, HVAC systems, UPS systems, solar inverters, automotive systems, AC-DC power adapters, and LED lighting systems. All of these devices need accurate, efficient, and reliable power factor correction. UCC39002DGK is designed to provide accurate PFC in a wide range of operating conditions.

The UCC39002DGK works by regulating the current waveform in the AC power line and adjusting the line voltage to reduce the amount of harmonic distortion, improve the power factor, and maximise power conversion efficiency. The device uses a proprietary control loop to effectively control the input current and voltage waveforms, as well as the output power factor. It also includes a protection circuit which monitors the status of the system and shuts down the power supply in case of an over- or under-voltage condition and other fault conditions.

UCC39002DGK integrates an input voltage range up to 200V and provides a near unity-power factor in all load conditions, nominal and low-load. It features adjustable current-mode control and digital correction of input voltage and current magnitudes, hence it can be optimally adjusted to multiple power factor correction applications. It has a wide range of control options and it is suitable for both single- and multi-phase applications. Also, it provides an enhanced current-mode feedback adapted specifically to the PFC duty cycle – which allows for greater accuracy of current regulation under all load conditions.

The UCC39002DGK provides an integrated double-shielded gate driver that is dedicated to driving power MOSFETs in half-bridge PFC topology. Additionally, the built-in thermal protection prevents the device from overheating, so that the system is not affected by any temperature-related effects. It also provides adjustable over-current protection and over-voltage protection for added system safety.

UCC39002DGK is an advanced, high-voltage current-mode power factor correction controller with integrated double-shielded gate driver technology. This PMIC is optimal for high-density, high-efficiency applications that require precise and reliable power management. It offers superior performance, low-power operation, wide operating range, and a high level of accuracy and reliability.
