Quantifying the value of wide VIN

Rate this Entry
-Excerpt from E2E TI Blogs -
When designing a power supply, one of the challenges designers often face is dealing with voltage transients. It is important to protect circuitry from voltage spikes greater than the rated input voltage (VIN) of the integrated circuit (IC). When dealing with voltage transients, designers have a choice between using a DC/DC converter on the front end of the system with a wide-enough input voltage range to cover any transients, or a lower VIN DC/DC converter with additional clamping circuitry to provide transient protection.
