Empower Semiconductor announced they have achieved the world’s fastest transient response times in the integrated voltage regulator family of power management devices. The Empower IVR EP7010 is a 10A regulator that can regulate through a load step from zero to 10A in 500ns with <15mv droop, with no output capacitors.
Empower Semi’s patented digitally configurable hardware platform has simplified the adoption of DC/DC converters for designers. With a single footprint, no external components, extensive programmability, a wide range of current and output configurations, power designers can proliferate the EP70xx across nearly all designs and platforms. By having multiple entire power supplies in a single IC package, the usual concerns of component variation and sourcing, synchronization, and stability are all either eliminated or reduced significantly.
The EP70xx, Empower has achieved the total integration of a triple output DC/DC power supply with no external components into a single tiny 5mm x 5mm package, attaining up to 10x higher power density, 3x tighter accuracy during transients and 1000x faster dynamic voltage scaling than leading competitors.
System designers are leveraging the EP70xx’s tight voltage regulation through an ultra-fast load transient by lowering the operating voltage of the system. The power consumption of a system is directly proportional to the operating voltage. By narrowing the window required for the voltage variation without additional components, Empower’s IVRs have enabled 10% or more power savings and corresponding heat dissipation. This results in a two-fold benefit of reduction in cooling costs and improved performance.
The EP70xx family displays peak efficiencies of up to 92% with a nearly flat efficiency curve up through 10A of output current due to its unique architecture. The devices showcase 1,000x faster dynamic voltage scaling than competing products, enabling fast and lossless processor state changes that can save 30% or more of processor power.
EP70xx family is available with nine devices to choose from with up to three regulators per device. Outputs are available from 2A to 10A in a 5x5mm or 4x4mm package with a 0.75mm profile, which is 3-5x thinner than traditional integrated power modules and inductors. The products achieve a level of density and simplicity so high that they are also available in bumped die form for co-packaging with digital ICs, enabling full power management integration into an SoC.
