1/8 brick power module optimizes 5V bus voltage to match load
Ericsson Power Modules has designed its latest 1/8 brick power module for 5V intermediate bus voltages and other applications requiring a tightly regulated 5V supply.
PowerDI5 bipolars save board space
Size and thermal advantages of Diodes' PowerDI5 package produce space saving alternative to much larger SOT223 and DPAK products.
Li+ battery charger has GSM test mode in a 6mm2 TDFN
Maxim's MAX8922L 30V battery charger offers a GSM test mode to facilitate production-line testing and calibration of cell phones with Micro-USB connectors.
20V switching regulators simplify intermediate power bus, PoL designs
ADI's ADP2300/01 step-down dc-to-dc non-synchronous regulators feature internal compensation to enable design engineers to reduce power system design complexity while generating power conversion efficiencies of greater than 90 percent.
16-bit quad, SPI DAC with internal reference achieves +/-4LSB INL (Max)
Linear Technology has introduced the LTC2654, a quad voltage output 16- and 12-bit digital-to-analog converter (DAC family) with internal reference and SPI interface.
WLED flash driver improves picture quality in mobile phones
austriamicrosystems announced the AS3645, an inductive, ultra small, high-efficiency single/dual LED flash driver that it claims offers 25% higher output current than existing equivalents.
12-/8-channel system monitors integrate current monitoring and nonvolatile fault registers
The MAX16070 and MAX16071 from Maxim Integrated Products are flash-configurable system monitors that supervise 12/8 voltages plus one current. Designed to simplify power-management schemes in multivoltage systems, these devices feature an integrated current monitor, nonvolatile fault registers, and an easy-to-use graphical configuration tool.
Quad output 200W power supplies are compact
With a 3-in. x 5-in. footprint and a height of 1.32-in., Emerson's latest power supplies offer a power density of more than 10 W per cubic inch and are capable of achieving efficiencies of up to 84 percent at full load.
Fairchild minimizes power losses in multi-stage power supplies
Fairchild Semiconductor has developed a CCM PFC controller for 300W to 2kW power supply designs that bring high system efficiency, high power factor and low total harmonic distortion (THD).
60V DC/DC controller draws 50µA in battery-powered systems
Linear Technology has introduced a high voltage dual output synchronous step-down DC/DC controller that draws only 50 uA when one output is active and 60µA when both outputs are enabled.
Microsemi expands backlight controller line
Microsemi has introduced a new CCFL controller featuring mega-contrast dimming for 24-volt cold cathode fluorescent light (CCFL) inverter applications in small- to large-sized LCD displays.
Thin-film resistor offered as high-power, low-cost alternative to thick film
Stackpole Electronics' sulfur-resistant, thin-film chip resistor provides stability and long-term reliability in industrial applications
Agilent pads oscilloscope line
Agilent's 14 latest models in its InfiniiVision 7000 series mixed-signal and digital-storage oscilloscope portfolio offer bandwidths from 100 MHz to 1 GHz, a 12.1-inch display, and hardware-accelerated search and navigate capability.
Charger IC handles, balances serial supercapacitor pair
LTC4425 from Linear Technology Corp. charges from Li-ion battery, USB port, or DC rail; targets peak power, backup, and "dying gasp" applications.
6-channel system managers with nonvolatile fault memory facilitate diagnostics
Maxim Integrated Products' MAX16067/MAX16068 integrate nonvolatile fault registers to facilitate failure analysis and are available with an easy-to-use graphical configuration tool that simplifies diagnostics and configuration.
