Accurate Power Supply Sequencing Prevents System Damage
... Many complex systems—such as telecom equipment, memory modules, optical systems, networking equipment, servers and base stations—use FPGAs and other digital ICs that require multiple voltage rails that must start up and shut down in a specific order, otherwise the ICs can be damaged. The LTC®2924 is ...
