    Products Detail

    The PT8120 Excalibur™ power modules are a family of high-output, high-efficiency, fully integrated switching regulators (ISRs) designed for high-end computing and signal processing applications. Operating from a nominal +12V input, they deliver up to 30A output current at programmable voltages from 0.8V to 7.6V using a 5-bit VRM-compatible code. The modules feature a 2-phase multipole topology for superior transient response and low input current ripple. Key system integration features include over-current protection, thermal shutdown, standby on/off control, and output remote sense. The PT8120 family incorporates a state-of-the-art, multiple power path topology extending output current range while maintaining high efficiency up to 94%.
