    Description

    The PT4580 series is a single-output isolated DC/DC converter, housed in a 19-pin space-saving package. These modules are UL, CSA, and VDE approved for telecom applications, and rated at 3 W or 8A. The 18V to 60V input range allows easy integration into many distributed power applications which utilize 24V bus architectures.

    Standard output voltages range from 1.8V to 15V, and are each adjustable by up to ±10%. Operating features include a Remote On/Off control, an under-voltage lockout (UVLO), and a differential remote sense. Protection features include an output current limit, short-circuit protection, and over-temperature shutdown.

    A 330 uF output capacitor is required for proper operation.
