The UCC28085PWR is an integrated power-management solution for high-current applications, such as LED lighting and LED drivers. It’s a multi-channel voltage regulator controller with high integration and accuracy that can provide output currents up to 1.5A each. The UCC28085PWR integrates several controllers to control both AC-DC and DC-DC converters, and features wide input voltage range, high-efficiency, fast transient response, low noise, and very low standby power. In addition, it comes with high-virtually adjustable output voltage range and multiple safety protection features for reliable operation even at extreme conditions.The UCC28085PWR can be used in a variety of applications including LED lighting, LED drivers, high-current DC-DC applications, and AC-DC converters. It is suitable for powering a wide range of devices including industrial control systems, energy-efficient appliances, intelligent lighting systems, and more.The UCC28085PWR can be used in an AC-DC or DC-DC mode for a range of power-management solutions. In AC-DC mode, it can provide high-efficiency, fast transient response, and low output voltage ripple in order to maximize power savings. In DC-DC mode, it can provide high-accuracy, very low output noise, and excellent load and line regulation. It can also be configured to have different operating conditions based on the desired output voltage and current.The working principle of the UCC28085PWR is straightforward. When in AC-DC mode, the controller switches power from an AC line to DC output. The AC input voltage is rectified and filtered and then fed to an internal PFC stage, where it is regulated and forced to become a DC voltage. The AC line voltage is then connected to the internal high side MOSFET, which then switches the power from the AC line to DC output. In DC-DC mode, the same process is followed, but with the DC-DC converter controlling the voltage level of the output.Overall, the UCC28085PWR is a versatile and reliable integrated power-management solution for high-current applications. It can be used for AC-DC or DC-DC applications, and provides high efficiency, fast transient response, and low noise. With its wide adjustable output voltage range and multiple safety protection features, the UCC28085PWR is an excellent choice for powering high-current applications.
