Pin compatible hybrid digital and analogue point of load modules simplify designs
Renesas Electronics has launched two encapsulated hybrid digital DC-DC PMBus power modules with a power density of 115mA/sq mm and up to 95 percent peak efficiency alongside two pin compatible analogue versions.
the hybrid digital modules support the SMBus/I 2C/PMBus v1.3 protocols up to 1.25MHz with seven switching frequency options from 300kHz to 1MHz

The digital modules are supported by the PowerCompass tool to help designers identify the right power modules and other parts that match their specific requirements. Multiple power rails can be set up for more than 200 FPGAs, and designers can perform high-level system analysis and generate custom reference design files in minutes. The PowerNavigator tool works with PMBus, allowing power architects to set up hybrid digital power module telemetry, sequencing, and run-time configuration, while each module’s pin-strap configuration allows for standalone operation.

The ISL828xM hybrid digital power modules and ISL821xM analogue power modules are available now from Renesas distributors and are being shown at the APEC power conference in the US this week.
