Encapsulated 80A digital power module unveiled
Intersil has announced the first 80A fully encapsulated digital DC/DC PMBus power module that provides point-of-load (POL) conversions for advanced FPGAs, DSPs, ASICs, processors and memory.The ISL8273M is a complete step-down regulated power supply that delivers up to 80A output current and operates from industry standard 5V or 12V input power rails.
Multi-phase current sharing of up to four ISL8273M power modules enables power supply designers to create a 320A solution with output voltages as low as 0.6V. Housed in a compact 18mm x 23mm module, the ISL8273M delivers the industry’s highest power densityA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitors and performance for increasingly space-constrained data center equipment and wireless communications infrastructure systems.The ISL8273M digital power module leverages a patented ChargeMode control architecture that delivers up to 94% peak efficiency and better than 90% efficiency on most conversions. It also provides a single clock cycle fast transient response to output current load steps common in FPGAs and DSPs processing power bursts. The ISL8273M’s compensation-free design keeps the device stable regardless of output capacitor changes due to temperature, variation or aging while eliminating the need for an external discrete compensation network.The 80A ISL8273M delivers 2x higher output current than competing power modules. Its proprietary High DensityA figure of merit usually expressed in Joules per cubic inch for capacitors Array (HDA) package offers unmatched electrical and thermal performance through a single-layer conductive package substrate that reduces lead inductance and dissipates heat primarily through the system board. The ISL8273M is built on Intersil’s fourth generation digital controller technology and is pin-for-pin compatible with the 50A ISL8272M. It expands Intersil’s existing 6A – 50A digital power module family, giving customers an easy migration path to higher current rails. These fully encapsulated power modules are compatible with all industry pick and place equipment for full manufacturing automation.
