The IPM- C Series POL converters

The IPM Series, single output, non-isolated point of load DC/DC converters, are the latest offering from a world leader in power systems technology and manufacturing ― Delta Electronics, Inc. They operate from a 3V~5.5V (IPM04C) or an 8V~14V (IPM12C) source and provide a programmable output voltage of 0.8V to 3.3V(IPM04C) or 0.8V to 5V(IPM12C). With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performance, as well as offering extremely high reliability under highly stressful operating conditions. All models are protected against abnormal input/output voltage and current conditions.

This document guides the user through the evaluation procedure to qualify a POL module. The data shown in this Evaluation Procedure is for the SIP and SMT Package Type POL evaluation board. Please refer to the appropriate technical data sheet for detailed performance and technical information for the specific POL units.
