Maxim forays into digital power

"Unlike competing technology, Maxim's InTune digital power technology is not an iterative tuning technique. It is deterministic and resolves several limitations present in today's digital power solutions," Templeton said. "Unlike PID-based solutions, the loop used by Maxim's InTune digital power technology provides seamless small- and large-signal response without the need to cross back and forth between linear and non-linear modes. This enables loop response up to 10x faster than competitors and does not require any user-set thresholds. In fact, the PWM controllers used by Maxim's InTune digital power technology are even faster than their analogue equivalents."

Meanwhile, Maxim has recently expanded its product efforts on other fronts. It recently announced the creation of highly-integrated power SoC devices. These new products integrate power management and mixed-signal functions such as digital audio, a high-speed interface and a touch-screen controller on a single chip. This will enable high performance, as well as thinner and smaller form factors in smartphones, tablets and e-readers, according to Maxim.

Separately, the company has also rolled out the MAX11855 and MAX11871 projected capacitive touch-screen controllers, offering 4-point and 10-point touch detection with industry-leading sensitivity and noise immunity performance.

It also recently introduced the MAX44007/MAX44009 digital ambient-light sensor (ALS) ICs with an adaptive-gain block. Designed using the company's proprietary BiCMOS technology, these ICs integrate two optical sensors, an ADC, and digital functionality into a tiny 2mm x 2mm x 0.6mm package.

The MAX44007/MAX44009 consume 100x less power than the nearest competitive product. They offer an interrupt function that constantly measures the amount of light and reports to the MCU when the measurement passes the threshold. This functionality extends power savings by reducing the frequency of I�C communications.

The MAX44007/MAX44009 are well suited for applications such as tablet and notebook PCs, smartphones, TVs, digital lighting-management systems and light-intensity monitoring applications.

Recently, analogue chipmaker Maxim unveiled what it called "the new Maxim" or ''Maxim 2.0.'' Actually, "Maxim 2.0," the company's business strategy, was set in motion back in 2000 and expanded in 2007. As part of the evolving and on-going plan, the analogue chipmaker has remade the company and shaken up the corporate culture.
