Lighting management unit reduces smart phone design time
Given the complexity and diversity of feature sets found in today’s cell phone product lines, designers can gain tremendous advantage in terms of design time and cost by using the same power management solution in multiple products. By delivering industry-standard I2C programmability across nine different LED combinations and I2C control across 16 different voltage settings for each LDO, AnalogicTech’s AAT2862 provides the level of versatili...
Zero Volt Input DC Electronic Loads
Kikusui’s DC Electronic Loads prove to be a popular choice for fuel cell and low voltage power supply testing. Kikusui currently have a choice of two Electronic Loads that are equipped to sink current at zero volts. The PlZ164WA Bench type DC Load and the PLZ70UA modular electronic load.
Tiny TI power circuit simplifies USB battery charger design
TI has introduced today the industry’s smallest 1.1-A Li-Ion linear battery charger with integrated 50-mA low-dropout regulator to support mobile phones and other handheld electronics. The new bq25040 comes in a small 2 mm x 3 mm package, and can regulate voltage within one-percent accuracy from a USB port or AC adapter. The device’s integrated LDO allows a mobile application to power up instantly from an external power source, even w...
Murata Power Solutions announces 5V additions to OKAMI family
The latest expansion of Murata Power Solutions’ Okami non-isolated single point-of-load (PoL) DC/DC converters sees the introduction of 3A and 5A modules with a 5V nominal input. The new parts complement the 12V input 3A, 5A, 10A and 16A modules recently introduced and give designers an even greater choice of alternatives to discrete design in providing high efficiency Point-of-Load (PoL) power for their embedded applications.
Complete lithium-ion Battery Monitor in 3mm x 3mm Package
Maxim has introduced the DS2741 current monitor/accumulator for cost-sensitive, lithium-ion (Li+) applications. The industry's first battery-monitoring IC to incorporate a high-side, current-sense resistor, this 3mm x 3mm device saves valuable real estate in space-constrained applications. Its unique topology allows users to connect the DS2741 directly to the power source to detect downstream failures and trigger appropriate corrective action.
Fairchild's Reference Design Simplifies DC-DC Conversion Designs
Fairchild Semiconductor has made it easier for designers of telecom, servers, set-top boxes and other consumer applications to develop a more efficient and compact solution with this synchronous Buck regulator reference design. The RD278 features the FAN21SV06, a single supply, highly integrated 6A synchronous Buck solution that enables designers to reach high levels of efficiency in less space.
IR Introduces Automotive-Qualified Dual Low-Side Driver IC
International Rectifier has introduced the AUIRS4427S dual low-side driver IC for low- mid- and high-voltage automotive applications including general purpose motor drives, automotive DC-DC converters and hybrid powertrain drives.
Maxim's Low-Noise Step-Up Converter Delivers Up to 600mW
Maxim has introduced the MAX15032, constant-frequency, pulse-width modulated (PWM), low-noise step-up converter. Designed for low-voltage systems that require a locally generated high-voltage output, this device integrates a high-voltage DMOS power switch, allowing it to boost the output up to 36V and deliver 600mW (max) of power.
