6 FAQs about [Reasons for the integrated power supply battery to run out of power]

Why is my power supply blown?

However, in some other designs of power supplies, the power section components seem to be easily blown when there is a short circuit either in the secondary side or the load. 4) Bad corresponding components- For example, if the power FET is shorted, most of the time the power IC could be shorted too.

How have battery-powered systems changed over time?

Use of battery-powered systems have expanded as consumers have migrated to portable phones, MP3 players, digital cameras, and more. This articles is part of the Power Management Series in the Power Management section of our Series Library. Download this article as a .PDF eBook.

How does a power supply protection circuit work?

The protection circuit seems to be able to detect a short circuit and shutdown the power supply thus saving the power supply from destruction. However, in some other designs of power supplies, the power section components seem to be easily blown when there is a short circuit either in the secondary side or the load.

What causes a power IC to fail?

Finding the root cause can be tricky, especially if it concerns a sporadic failure that cannot be repeated. At Richtek, we have analysed many failure cases. We found that most power ICs are damaged because of Electrical Over Stress (EOS) on the IC input supply pins. But how does EOS happen and how does the IC actually fail?

Why are battery-powered systems becoming more popular?

Use of battery-powered systems have expanded as consumers have migrated to portable phones, MP3 players, digital cameras, and more. One reason for this growth has been the availability of batteries and power-management ICs that provide the required support for increasingly complex electronic systems.

How does a power converter affect battery run time?

One design consideration is reducing power dissipated by the power converter, which in turn increases battery run time. Most converter ICs have a shutdown pin that disables the output voltage, cutting battery drain. This can be done in many systems that have a normal “sleep” mode.
