Unique gearbox for heavy vehicles launched by Volvo Trucks
Volvo Trucks is now launching I-Shift Dual Clutch - the first automated transmission for heavy vehicles with a dual clutch system. Thanks to power-shift gear changes torque is maintained without any interruption in power delivery and, as a consequence, the truck does not lose any speed during gear changes. For the driver, the result is more comfortable and efficient progress on the road.
40V amplifier significantly improves system performance
Analog Devices has introduced the industry’s fastest operational amplifier for driving heavy loads at high voltage and high output current, including piezoelectric transducers, PIN diodes, laser diodes, power FETs, coils and CCDs. The 40-V ADA4870 amplifier delivers over 1A of output current at more than twice the slew rate (2500 V/s) of competing high output-power amplifiers, enabling applications including higher accuracy, high-intensity ...
AC-DC UPS series provides up to 300W DC output
Powersolve announces the PFD Series, a “no break” power system designed to provide constant DC power without interruption. These 19in rack mount units are available with either 12, 24 or 48VDC from an input voltage of 180 to 264VAC (50/60Hz) They can be used as both a power supply and a charging device. Models in the PFD Series are available with either 150 Watts or 300Watts output power.
Buck controller optimises notebook performance
The AP3591 single-phase, synchronous step-down controller from Diodes Incorporated is designed to provide enhanced transient response and output accuracy for low-voltage regulation in notebooks and all-in-one PCs. Operating at a resistor-programmed fixed frequency between 100kHz to 700kHz, the device’s adaptive constant-on-time control algorithm is capable of handling very wide input/output voltage ratios and helps reduce external component...
Device targets China tablet and smartphone market
Dialog Semiconductor continues to expand its Rapid Charge mobile device adapter solutions with the launch of its MediaTek Pump Express Plus-compatible iW1788 AC/DC controller. Pump Express Plus is MediaTek’s proprietary fast charge protocol that supports high power chargers with an output of 15W or more and reduces typical mobile device recharge times by up to 50%.
45V input 200mA LDO offers active output discharge
Linear Technology announces the LT3063, a high voltage, low noise, low dropout voltage linear regulator with active output discharge. The IC delivers up to 200mA of continuous output current with a 300mV dropout voltage at full load. The LT3063 includes an internal NMOS pull-down that discharges the output voltage if either the SHDN pin is driven low or the input voltage is turned off.
AC/DC Power Supplies Ensure Continuous Operation
CUI have announced the release of a new AC/DC power supply family targeting applications that demand 100% uptime. Available in 75 W, 100 W and 155 W configurations, the PSF series is designed with built-in battery charging and back-up functionality. Under normal operating conditions, the units are able to charge the stand-by battery and also supply direct power to the load.
