6A voltage regulator fits in a cubic millimetre

December 06, 2017 // By Nick Flaherty
Endura Technologies has launched a 3-phase 6A switching regulator inside a package that measures less than one cubic millimetre.

The ET7700 product family is the industry's first 28nm embedded voltage regulator (eVR) and is integrated inside the SoC package within 5mm 2 area and less than 200μm height including inductors. The family will include a fully integrated stand-alone module in 2018.

"This milestone is an important achievement and the culmination of several years of intense design, development and concept validation enablement effort with various partners," said Taner Dosluoglu, CEO of Endura Technologies. "We have designed the most advanced embedded switching voltage regulator that delivers high performance while using very small inductors (<6nH) and capacitors (<0.47uF) providing high efficiency, small form factor (<1mm 3), PCB area and BOM savings, as well as support for high-definition DVFS." 

The 70MHz-130MHz programmable DCDC buck converter supports Dynamic Voltage Control (DVC) for DVFS, with a slew rate >500mV/100ns. It has a wide output voltage regulation range of 0.1V-1.1V and the efficiency is flat over the whole load range. It also supports automatic PFM/PWM operation and phase shedding without hysteresis and includes built-in fast digital current reporting in <1μs with no external components.

The small L/C components are ideal for land-side/top-side in-package integration and evaluation boards are available for testing and validation.

Endura is a fabless semiconductor company based in Dublin designing power management devices for embedded power management for very demanding system-on-chip (SoC) CPU type applications, as well as stand-alone power management integrated circuits (PMICs). It is a portfolio company of the Bridgewest Group.
