Features and Benefits

The LM5017SD/NOPB is an ideal voltage regulator for mobile applications. It offers two main features that make it a desirable choice for mobile devices. First, it provides superior light efficiency, allowing for more efficient operation and longer device battery life. Second, it can provide voltage regulation from both low and high voltages, allowing users to connect their device to different sources, from a wall power adapter to a computer USB port. Additionally, the LM5017SD/NOPB also offers low quiescent current and fast transient response, as well as a low gate charge and good switching frequency control.

Application Field and Working Principle

The LM5017SD/NOPB can be used in a variety of applications such as charging, powering, and voltage regulation. It is an ideal solution for mobile power enhancing devices that require both low and high voltage regulation. The LM5017SD/NOPB works by converting an unregulated input voltage into a regulated output voltage. This is done by switching the voltage at high frequencies (switching frequency up to 2 MHz) and by using synchronous rectification to improve power efficiency.The output voltage of the LM5017SD/NOPB is adjustable in three blocks: A low voltage range of 0.8 V - 2.3 V, a medium voltage range of 2.3 V - 5.0 V, and a high voltage range of 5.0 V – 24 V. The input voltage range is from 6 V - 40 V, and its start-up voltage is 0.9 V. The LM5017SD/NOPB allows for a soft-start time of 10 ms, and is capable of driving up to 2 A of continuous current.

Conclusion

The LM5017SD/NOPB is an advanced DC-DC switching regulator that is designed for mobile power applications. It offers superior light efficiency, a wide input voltage range, and a wide output voltage range. It also requires no external components and offers a fast startup time and low quiescent current. This makes the LM5017SD/NOPB an ideal voltage regulator for demanding mobile power applications.
