Eval boards check power modules for trimming, sequencing, soft starts and sensing functions
RECOM’s eval boards for the RPM‐1.0, RPM‐2.0, RPM‐3.0, and RPM‐6.0 buck regulator series generate a constant output voltage with an output current up to 6A from an external DC source. The multitude of functions offered by the RPM power modules such as trimming, sequencing, soft‐start, enable, and sensing can be evaluated. More importantly, the behavior […]
Automotive-grade buck-boost ICs ensure stable performance with low current consumption
ROHM today announced the availability of a buck-boost power supply chipset that provides the lowest current consumption in the industry along with stable performance (transient response characteristics) in automotive ECUs (Electronic Control Units) for cluster panels and gateways used in start-stop vehicle systems. The chipset integrates a buck DC/DC converter with boost functionality (BD8P250MUF-C) and a […]
