The dual ISL8274M operates from a 5V or 12V power rail, providing two 30A outputs and up to 95.5% maximum efficiency in a compact 18mm x 23mm² footprint. The new ZL9024M operates from a 3.3V rail and delivers 33A of power in a 17mm x 19mm² footprint. They offer point-of-load (POL) conversions for advanced FPGAs, DSPs, ASICs, and memories used in servers, telecommunications, data communications, optical networks, and storage equipment. Both devices are user-friendly PMBus configurable power supplies that include a controller, MOSFET, inductor, and passive components encapsulated within a single module, increasing board space and reducing the bill of materials (BOM).
 
The ISL8274M and ZL9024M digital power modules leverage Renesas' patented ChargeMode™ control architecture, delivering the highest efficiencies of over 90% in most conversions. These power modules also provide fast, single-clock-cycle transient response to the output current load steps common in FPGAs and DSPs processing burst power. Their uncompensated design keeps the modules stable regardless of output capacitor changes due to temperature, variation, or aging. Eliminating the need for an external discrete compensation network also saves board space and reduces bill of materials costs. The ISL8274M supports input voltages from 4.5V to 14V, while the ZL9024M accepts input voltages from 2.75V to 4V. Both modules offer adjustable output voltages as low as 0.6V.
 
The encapsulated modules utilize Renesas' patented High Density Array (HDA) packaging, which delivers unparalleled electrical and thermal performance through a single-layer conductive substrate that reduces wire inductance and dissipates heat primarily through the baseplate. The HDA's copper lead frame structure allows the modules to operate at full load across a wide temperature range without airflow or heatsinks. The ISL8274M and ZL9024M also offer several protection features that ensure safe operation under abnormal operating conditions, further enhancing their robustness and reliability.
