Renesas Electronics announced a pair of new encapsulated hybrid digital DC/DC PMBus™ power modules, the 10-amp ISL8280M, and 15-amp ISL8282M. The hybrid digital power modules offer best-in-class power density of 115mA/mm2 in a 12mm x 11mm package, with up to 95 percent peak efficiency. They are complete single-channel, synchronous step-down regulated power supplies that operate over a wide input voltage range of 5V to 16V.
Also announced today are the new ISL8210M and ISL8212M analog power modules, offered in the same pin-to-pin compatible 12mm x 11mm package with 10A and 15A of output current, respectively. The hybrid digital and analog power modules provide point-of-load (POL) conversion for advanced FPGAs, DSPs, ASICs, and memory used in servers, storage, optical networking, telecom, and a broad range of space-constrained industrial applications. Each device integrates a PWM controller, MOSFETs, and inductor inside a new thermally optimized, Grid High-Density Array (GHDA) encapsulated module. To complete the power supply, designers simply add input and output ceramic capacitors.
The ISL828xM hybrid digital and ISL821xM analog power modules feature integrated LDOs that enable single-supply operation. They leverage Renesas’ patented R4™ high-speed control loop architecture with inherent line voltage feed-forward, providing designers a unique combination of ultra-fast load transient response and high noise immunity. Their proprietary Grid HDA package offers unmatched electrical and thermal performance through a single-layer conductive package substrate that efficiently transfers heat from the module to the system board, and dissipates it without requiring airflow or heatsinks – even under heavy load conditions.
“Our newest power modules expand Renesas’ growing portfolio, adding new capabilities to our performance analog module family and bridging the gap between them and our full digital power modules,” said Philip Chesley, Vice President, Industrial Analog and Power Business Division, Renesas Electronics Corporation. “The new hybrid digital power modules offer class-leading power density and efficiency not achievable with discrete components. Compared to competitors’ module designs, the new Grid HDA package makes it easier for customers to mount the module on their circuit board.”
