Ericsson BMR464 series

    Digital 40-50A POL

    BMR464 extends maximum output current of 3E second generation of Ericsson’s Point-of-Load voltage regulators from 20A to 50A. It offers easy paralleling and current sharing. Up to seven modules can be paralleled, offering a maximum output current of 350A.

    Key Features

    It features digital PWM with a Power Good (PG) pin, advanced paralleling, delay and ramp-up. The series also features non-linear transient response, and is PMBus read and write compliant.
    50A series also features Dynamic Loop Compensation (DLC).  

    Input: 4.5-14 V
    Output: 40/50 A
