Renesas Electronics Uses Scalable Digital Controllers For Industrial Applications, Communications, And Cloud Computing By Simplifying Power Supply Designs

Renesas Electronic Corporation, a supreme supplier of highly developed semiconductor solutions, recently came up with two brand new PMBusTM compliant, completely DC/DC controllers that offer single output POL (Point-Of-Load) conversions for general purpose system rails, network processors, ASICs, DSPs, and FPGAs. The ISL68300 with integrated ISL68301 and MOSFET with PMW eases out designing power supplies for wireless communications, factory automation equipment, wired communications, and data center. The ISL68300 is capable of driving discrete outer MOSFETs straightforward while ISL68301 easily teams with Renesas smart power stages as well as DrMOS power displays to design a full voltage regulator solution.

The ISL68301 and ISL68300 digital controllers showcases a high-speed current share bus that syncs up to eight controllers in a 8-phase 240A+ current share configuration. Both these controllers apply Renesas’ digital ChargeModeTM control modulation, that interacts with load transients inside a single switching cycle and offer an inherent stable control loop without needing any external compensation. This modulation architecture brings down output capacitor desires and brings down Vout overshoot and undershoot.

As Mark Downing, the Vice President of Core Power Solutions Division from Renesas Electronic Corporation, puts it, “The scalability of the ISL68300 and ISL68301 single output digital controllers provide industry leading performance and support a wide range of load currents. The new digital controllers complement our award-winning digital dual-output multiphase controllers, giving customers everything they need to power all the rails in their next-generation systems.”

Engineers can always make use of PowerNavigatorTM GUI with the ISL68301 and ISL68300 to ease up power supply setup, monitoring, configuration, sequencing, and all other device parameters as well as telemetry. The full schematic designs can be finished within minutes, and GUIs with PMBus make it quite simple to control the complete design and alter features without soldering parts or rework.
