POL regulator features Dynamic Loop Compensation

POL regulator features Dynamic Loop Compensation
The Ericsson 3E series BMR464-50A is a third-generation digital point-of-load (POL) regulator that features Dynamic Loop Compensation (DLC) and also extends output current up by 25% to 50A from the 40A offered by the BMR464-40A, yet it comes in a fully compatible footprint. Embedding the latest Dynamic Loop Compensation technology, the BMR464-50A runs the DLC algorithm as default following the enabling of the output.
