Semtech Awarded “Product of the Year” by EN-Genius Network for LED Driver SC5010

Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced it has been awarded “Product Of The Year” by EN-Genius Network for the best LCD panel LED backlight driver SC5010.  According to the publication, Semtech’s SC5010, a boost LED driver for LCD backlighting was awarded for exceptionally innovative and market-forward product. The SC5010 is an 8-channel white LED driver with an innovative PWM phase-shift dimming control that uses very low-profile inductors (1mm), allowing LED drivers to be built directly into the LCD panel in Ultrabook PCs and ultra-mobile PCs (UMPC) for displays as thin as 4mm. It also enables ultra-thin LCD displays with longer battery life in tablet, automotive, and other mid-size display applications.

“The SC5010 offers a truly breakthrough approach for designing backlight modules in ultra-thin displays without sacrificing efficiency,” said Athar Zaidi, Director of Marketing in Semtech’s Power Management Group. “It gives designers an innovative approach that eliminates audible noise and reduces EMI, both common problems when using conventional boost-based LED drivers.”

The SC5010 delivers higher efficiency when using the same size inductors as existing phase-shifted LED drivers, but unlike these devices, the SC5010 can operate with inductors that are up to 10X smaller while maintaining high efficiency. This enables LED drivers to be designed directly into the panel, even in ultra-thin applications. This is due to the sophisticated control loop architecture, which allows the use of inductors as small as 2.2µH (1mm height). The phase-shifted technology in the SC5010 also minimizes demand on the input and output capacitance offering the high efficiency of conventional non-phase shifted switching regulators, with significantly lower noise, less EMI (electromagnetic interference), and no need for noise filtering components.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
