LV5050NV-TLM-E is a DC DC switching controller equipped with a variety of functions, allowing it to feasibly deliver high-performance current from high-current multi-source supplies, such as rechargeable battery, load supply, and solar panels. The controller is broadly used in electronic devices, typically to regulate the current from multiple sources of power and achieve a desired output level. It works well in conditions with up to 50V maximum input voltage and up to 500mA output current.
Application Fields
The LV5050NV-TLM-E is used in many applications, including:
- Consumer electronics such as mobile phones, tablets, and digital cameras
- Industrial and automotive applications where a power-saving feature is sought
- Solar-powered applications in which the maximum power measurement method is desired
- Automotive power control and high-density current regulation
- High accuracy systems with additional output current protection features
Working Principle
The LV5050NV-TLM-E works on multiple power sources operating in a switching-regulation configuration. This means that when external voltages are present, the device is able to monitor and maintain output power within a predetermined range. When the input power varies, for example when the battery is discharged, the device can adjust the duty cycle to maintain output power accordingly. It can also switch between multiple sources where the output voltage is constant and a preset level of accuracy is met. This ensures that the load is always supplied with the optimum power source and the power drain never exceeds the output voltage or current, thereby avoiding potential DC-DC efficiency losses.
The LV5050NV-TLM-E also features several safety features such as overvoltage protection, overcurrent protection, and short-circuit protection. These features help protect the circuit from damage due to excessive voltage or current, which could otherwise cause malfunctions or even damage important components. The device is also equipped with a wide range of features that help respond to different load conditions, providing flexibility during operation. This is further enhanced by the controller’s low-noise operation that is suitable for noise-sensitive applications.
In summary, the LV5050NV-TLM-E is a reliable and efficient DC DC switching controller, providing many useful features for a range of purposes. It is capable of regulating the output power of multiple power sources, and its over-voltage and over-current protection features make it suitable for a number of applications. As such, it is a great choice for anyone looking to regulate multiple sources of power.
