Software Controllable Octal LED Driver for Portable Devices
Semtech Corp has announced the SC620, an octal, I2C-controlled LED driver. The SC620 is designed to provide regulated currents for powering a wide range of LEDs, including white, red, blue, green or yellow, with different forward voltages. The SC620 is designed to drive the LED backlights for small to medium size LCDs in portable systems that use rechargeable lithium ion/polymer batteries, but may also be applied in systems with a fixed 5V or 3...
Semtech - Single-Cell AA/AAA, 555-Like Analog Timer with Battery-Safe Operation
Semtech announced a sub-1 V analog timer platform that revolutionizes the conventional 555 timer for low-voltage, battery-operated small appliances. The new SX8122 analog timer offers the best-in-class battery life via its intrinsic 0.9 V operation, without the need for an external boost converter and inductor, saving board space and cost. It also adds low-voltage features to the legacy 555 timer, with one output that controls a DC motor or anoth...
JTAG ARM emulator adds Ethernet capability
Phaedrus Systems is now shipping the J-Link ARM Pro, a high performance JTAG emulator for a wide range of ARM architectures. Based on the successful SEGGER J-Link emulator, the J-Link ARM Pro has an Ethernet interface, allowing complete electrical isolation between host and target and remote operation, additional memory for increased firmware downloads and two additional LEDs to act as hardware status indicators.
RGB laser driver squeezes embedded pico projectors into a new class of consumer electronics
Maxim has introduced the MAX3600, a 3-channel RGB laser driver that enables the integration of high-resolution pico projectors into small-form-factor applications. Fabricated using Maxim's newest BiCMOS process, this device achieves very fast switching times of < 2ns to support high-resolution images up to 1080p (1920 x 1080 pixels) and WXGA (1400 x 768 pixels). Additionally, it eliminates the need for three discrete laser drivers, thus enabling ...
MAX6948B: WLED driver with PWM-controllable boost maximizes power efficiency
Maxim Integrated Products introduces the MAX6948B, a high-efficiency WLED driver with an integrated boost converter and five GPIO ports that can be used to drive LEDs (powered from an alternate power supply) in parallel. Capable of driving up to six LEDs in series, the boost converter allows PWM control of the boost voltage to maximize power efficiency. The I2C-programmable, 10-bit PWM signal enables 1024 levels of WLED intensity, thus providing ...
