Hybrid digital, dual PWM controller claims best in class reliability, efficiency
June 08, 2012 // Paul Buckley
Intersil Corporation has introduced a new green hybrid digital, dual PWM controller that is compliant with Intel's VR12/IMVP7 specification.
The ISL6367 incorporates a 6-phase PWM to control the microprocessor core or memory voltage regulator and a single-phase peripheral PWM voltage regulator for graphics, system agent or processor I/O. Additionally, the ISL6367 has simplified programmable functions and telemetry for optimal system flexibility. Intersil's proprietary hybrid digital approach eliminates the need for non-volatile memory (NVM) and firmware typically required by digital solutions, reducing cost, design complexity, manufacturing control and inventory requirements.
The ISL6367 features external programmability to support different platforms and designs and offers a best-in-class linear control loop architecture. The proprietary EAPP control architecture provides excellent current balance during high frequency transients and eliminates beat frequency oscillation.
The device offers digital power management benefits through its PMBus/SMBus/I2C compatibility.
Offering the highest efficiency from light to full load, the ISL6367 is compatible with phase doublers such as the ISL6611A and ISL6617, to double or quadruple the phase count (up to 24+4 phases).
Availability and Pricing
The ISL6367 is available now in 60-lead 7 x 7 QFN packages with prices starting at $3.75 each in 1,000-unit quantities.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
