USB µModule transceiver protects systems with galvanic isolation
Linear Technology introduces the LTM2894, a USB µModule (micromodule) reinforced isolator that guards against ground-to-ground voltage differentials and large common mode transients. A rugged interface and internal isolation makes the LTM2894 ideal for systems implementing USB in harsh industrial or medical environments where protection from high voltages is required.
Synchronous step-down regulator delivers over 93% efficiency
A 600mA, 100V input capable synchronous step-down switching regulator has been announced by Linear Technology Corporation, the LT8630. Synchronous rectification delivers efficiency as high as 93% while Burst Mode operation keeps quiescent current under 7µA in no-load standby conditions.
Current-shunt monitor improves efficiency and accuracy
Texas Instruments (TI) has introduced a current-sense amplifier for in-line motor phase current measurement that improves overall motor efficiency, compared to existing current-sense amplifiers. The INA240 offers enhanced Pulse-Width Modulation (PWM) rejection for systems running at up to 80V to support a variety of applications such as motor control, solenoid control and power delivery systems.
Smart battery guide will reduce costly design errors
An infographic has been published by Accutronics, offering guidelines for Original Equipment Manufacturers (OEMs) on what should be considered when specifying a rechargeable smart battery to power their next product. The infographic highlights the importance of considering batteries at the earliest possible stage in the development process.
Patented technology improves IGBT performance; reduces power loss
The first device in the 650V H2-series IGBT family has been announced by Alpha & Omega Semiconductor. It is optimised for high speed switching performance.
AC/DC power supplies suitable for space-constrained applications
CUI Inc announced a family of ultra‑compact AC/DC power supplies in an open frame SIP package. The 3 W and 5 W configurations of the PBO series measure as small as 35 x 11 x 18 mm (1.38 x 0.43 x 0.71 in), allowing them to occupy less board real-estate than other power solutions. The 3 W models are also available in low-profile, right-angle versions measuring as small 35 x 18 x 11 mm (1.38 x 0.43 x 0.71 in), making them ideal for applications wh...
Glow-in-the-dark dye could fuel liquid-based batteries
Could a glow-in-the-dark dye be the next advancement in energy storage technology? Scientists at the University at Buffalo think so. They have identified a fluorescent dye called BODIPY as an ideal material for stockpiling energy in rechargeable, liquid-based batteries that could one day power cars and homes. BODIPY—short for boron-dipyrromethene—shines brightly in the dark under a black light.
