The low voltage – high amperage supplies the next generation of microprocessors, gate arrays and integrated circuits with reliable power. The TXS series features input undervoltage lockout, plus overload and overtemperature protection and its input-output voltage combination is ideally suited for Distributed Power Architectures (DPAs).
