CHiL Semi Announces Efficiency Breakthrough for Computing Voltage Regulator Solutions for CPU, GPU, & DDR applications

February 25, 2010 by Jeff Shepard

CHiL Semiconductor Corp. announced what it describes as a breakthrough in high efficiency computing voltage regulator (VR) solutions for CPU, GPU, and DDR applications. Now configured to optimize efficiency from the lowest idle state to the highest operating state of today’s high performance server, graphics and desktop solutions, CHiL’s next generation true-digital power algorithms have increased efficiency up to 15%, especially at low loads.

"CHiL’s engineering team is completely focused on delivering the industry’s best efficiency," said Chief Executive Officer Ram Sudireddy. "While some solutions provide either high efficiency or exceptionally fast response time, CHiL’s true digital power techniques deliver both. CHiL’s solution reaches new levels of overall efficiency and power savings and the ultimate in flexibility by balancing cost, efficiency, size and performance. This allows our customers to ultimately control their product performance."

When applied to server class products, ChiL states that its efficiency-improving techniques can save up to 85W per server card at peak operation, and 40W during typical operation. In data centers that operate 24/7, this translates to annual savings of 350 to 700kWh per board, resulting in significantly reduced power, heat and operating costs.

Throughout the entire operating range, CHiL’s variable gate drive algorithm adjusts the gate drive voltage to minimize gate drive losses at low operating loads, and optimize conduction losses at high loads.

In idle state, CHiL’s proprietary discontinuous-mode operation requires no sensing circuitry and can be configured digitally to optimize performance. In low current modes, the automatic dynamic phase control optimizes the number of operation phases to minimize power losses. Simultaneously, the non-linear digital transient response, known as adaptive transient algorithm, or ATA, can easily respond to the processor, instantly increasing its load.

CHiL states that its true-digital algorithms can be applied to readily available off-the-shelf components, and do not rely on specific, often costly, semiconductor products to achieve these power savings.
