The UCC2805N is a component of a switcher-mode pulse-width modulation DC-DC controller, which can accept input voltage power ranging from 8V to 80V, and regconize a range of output current up to 10A. This component is an improved version of the UCC28050, so the UCC2805N and its predecessor share similar application fields and working principles. The primary application field of UCC2805N lies in DC-DC controller circuits, such as DC-DC converters, frequency enhancement circuits, LED drivers, LED lighting accessories, security camera lights, and many other high frequency power solutions. This means the UCC2805N can be used in a wide range of products, and is likelly to become a go-to component by system designers due to its flexibility.The UCC2805N is composed of several internal functions. Starting with the power input, the current received signals are converted into voltage signals, then processed by the hysteresis comparator for the necessary waveform reshaping. Then, power MOSFETs or other power switches are used to create the required output signal based on the processed waveform. Finally, when the power output is generated after undergoing the signal reshaping, it is ready to be used as the bus voltage in the target circuit.In addition, several distinct features are also equipted in the UCC2805N to further enhance its performance. One large feature of the UCC2805N is the Advanced Current-Mode PWM Control, due to its ability to accurately generate the necessary waveforms needed by the target circuit. Another feature that greatly improves performance is the Frequency-Locked Loop, which increases the stability of the PWM control with seamless accuracy.Furthermore, two independent motor control pins are also included, allowing the UCC2805N to accurately control multiple motors at once. And lastly, several built-in protection functions are used to make sure the components will last longer under extremely harsh conditions, these functions includ surge current protection, over temperature protection, and overvoltage protection.Overall, the UCC2805N is an extremely flexbile DC-DC controller for a wide range of applications. It boasts several distinct features that increase its stability and performance, and is protected by sevaral safe guards to prevent damages caused by extreme temperatures, voltages, and currents. Therefore, the UCC2805N is an ideal choice for DC-DC power solutions, LED lighting accessories, frequency enhancement designs, and many other electronic systems.
