Power Boost is particularly beneficial in applications with high inrush current or multiple parallel loads, where short-duration peak demand can exceed the nominal output of the power supply.

For example, in an EV charging terminal, the power supply is responsible for powering control systems and safety electronics. Such systems may include multiple DC/DC converters and point-of-load (POL) converters operating in parallel. Each converter generates its own inrush current during startup, and when combined, the total inrush current can become significantly higher than the rated output of the power supply.

In these situations, Power Boost capability—such as 150% output for up to 5 seconds—allows the power supply to handle the cumulative surge current without voltage drop or system instability. This can help reduce or eliminate the need for additional components such as active inrush current limiters, and may also simplify system design by avoiding complex power-on sequencing.

As explained in What is Power Boost in a Power Supply and How Does It Work?, this short-duration reserve power is designed specifically to handle transient conditions like startup surges.

Additionally, selecting a suitable model with sufficient Power Boost capability is important—see Which of Our Power Supplies Have Power Boost? for supported products.
