Piezoelectric Energy Harvesting Power Supply
sobota, 09 stycznia 2010 09:03

Linear Technology announces the LTC3588-1, a complete energy harvesting solution optimized for low energy sources, including piezoelectric transducers. The LTC3588-1 integrates a low-loss, full-wave bridge rectifier with a high efficiency buck converter to harvest ambient vibrational energy via piezoelectric transducers and then convert it to a well-regulated output to power application microcontrollers, sensors, data converters and wireless transmission components. The LTC3588-1 operates from an input voltage range of 2.7V to 20V, making it ideal for a wide array of piezoelectric transducers, as well other high output impedance energy sources.

LG launches 120MW line for solar cells, modules
czwartek, 07 stycznia 2010 16:09

LG Electronics is readying to launch a new crystalline silicon solar cell production line in Gumi, about 200km southeast of Seoul, South Korea, with 120MW capacity and projected annual output of ~500K solar modules. A second line will follow in 2011, doubling output to 240MW, with an investment of $220M. The operation will be managed by LG's "air conditioning" company, which has a background in managing energy resources and "developing environmentally responsible solutions for homes and businesses," the company noted in a statement.

Simultaneous-sampling ADC provides "true" 16-bit performance for polyphase power-grid designs
środa, 06 stycznia 2010 10:41

Maxim Integrated Products introduces the MAX11046, an 8-channel, 16-bit simultaneous-sampling ADC. An unique architecture (patent pending) provides an ultra-low-noise, on-chip, negative supply voltage. The high impedance input eliminates precision external buffers on each channel, while the bipolar input saves a level shifter. Furthermore, simultaneous sampling eases the typical requirement for phase-adjust firmware and thus speeds end designs and time to market. Together these benefits simplify the design challenges for power-grid monitoring and measurement equipment while also providing unprecedented performance, and saving cost, area and power.

New Linear step-down switching regulator with 1.2 A output
wtorek, 05 stycznia 2010 12:03

Linear Technology has announced the LT3663, a 1.2A, 1.5MHz monolithic current mode step-down switching regulator with a programmable output current limit. Its wide operating input voltage of 7.5V to 36V makes the LT3663 ideal for a variety of input sources, including unregulated 12V wall adapters, 24V industrial supplies, Fire Wire, as well as automotive applications. Onboard input overvoltage lockout protects the device through input transients as high as 60V, such as those commonly found in automotive applications.
