    Products Detail

    The PT8120 family is designed to power high-end computing and signal processing applications, all of which demand high output currents at low supply voltages. These modules operate from a nominal input voltage of +12V to provide up to 30A of output current at output voltages as low as 0.8V. The output voltage is programmable via a 5-bit input code. The PT8120 family incorporates a state-of-the-art, 2-phase, multiple power path topology, extending the output current range while providing superior transient response and input current ripple performance. Features include over-current protection, thermal shutdown, standby on/off control, and output remote sense.

    Key Features

    • Single Device: 30ADC, +12V-Input, High Efficiency: 92% @3.3V, Programmable Output: VRM Compatible 5-bit Codes, Multiphase Topology, Output Remote Sense, Over-Current Protection, Thermal Shutdown, Standby On/Off Control, Space-Saving Package, Solderable Copper Case
