Renesas announced two new fully encapsulated digital DC/DC PMBus® power modules that deliver the highest power density and efficiency in their class.
The dual ISL8274M operates from a 5V or 12V power rail, provides two 30A outputs and up to 95.5% peak efficiency in a compact 18mm x 23mm footprint. The new ZL9024M operates from a 3.3V rail and outputs 33A of power in a 17mm x19mm footprint. They deliver point-of-load (POL) conversions for advanced FPGAs, DSPs, ASICs and memory used in servers, telecom, datacom, optical networking and storage equipment. Both devices are easy-to-use, PMBus-configurable power supplies that include a controller, MOSFETs, inductor and passives encapsulated inside a module that increases available board space and reduces bill of materials (BOM).
The encapsulated modules use Renesas’ proprietary High Density Array (HDA) package, which offers unmatched electrical and thermal performance through a single-layer conductive substrate that reduces lead inductance and dissipates heat primarily through the system board. Both modules offer adjustable output voltages as low as 0.6V.
