Ericsson Power Designer (version 1.4) features advanced loop compensation functionality that makes it easy to simulate output capacitors and filtering networks such as PI filters on the output of 3E* Point-Of-Load (POL) DC/DC converters, and to optimize loop response without hardware modification for the end application.

Sweden : Ericsson adds simulation to DC/DC Power Designer software, reducing time-to-market

The industry has reached the point where traditional architectures, based upon resistor--capacitor (RC) pi filters, impose limitations in terms of signal integrity and system robustness, and advanced integrated passive solutions based on a new architecture are required.
