Ericsson BMR464 series

40A/50A 3E 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

  • 3E POL connect
