The AL5812 delivers a constant current of up to 150mA and provides designers of low-current illumination and signage applications with a simplified circuit solution for accurately controlling 1/2W LEDs. Housed in a small-footprint, thermally enhanced SM package option, the driver is able to meet power handling requirement...

Power Integrations has launched an 18W non-isolated A19 LED driver with 88%-efficient. It’s designed for a 100W incandescent bulb replacement and will support low-line (90 VAC to 135 VAC) operation. According to Andrew Smith, product marketing manager at Power Integrations, "The lighting industry typically asks for 80% efficiency for drivers targeting 60W A19 bulb replacements. To achieve viable LED-based replacements for 75W and 100W bulbs, much higher efficiency is needed in order to reduce the heat dissipated by the driver. The 88% efficiency...

Power Integrations has added two new devices to its LinkSwitch™-PH IC family. The new devices allow commercial lighting applications up to 75 W to benefit from single-stage design, reducing BOM cost and enabling a smaller driver with high efficiency. LNK410EG (dimming) and LNK420EG (non-dimming) provide a constant-current output with a PF- corrected and low THD input. The capabilities of the new devices are showcased in RDR-290, a reference design describing a single-output driver for high-bay lighting. RDR-290 is 92.2% efficient at 230 VAC...

O2Micro® International Limited has developed the OZ8022M High Brightness Offline LED Driver Controller. O2Micro's patented Free Dimming technology enables LED bulbs to dim using any on/off switch, thus eliminating cost, installation and compatibility problems associated with traditional incandescent dimmers. O2Micro's patented Free Dimming technology works with any on/off switch, including wall toggles, paddle switches, pull cords, rotary switches and other types of on/off switches commonly found on walls, extension cords and table/desk lamps. Acc...

GlacialPower a sub-division of the experienced technology manufacturer GlacialTech Inc., is pleased to announce a compact GlacialPower LED drivers with high power efficiency – GP-LS50PH-142C, GP-LS70PH-100C, GP-LS100PH-142C and GP-LS100PH-71C. With the compact dimensions of 177 x 57 x 37mm (LxWxH), these 4 LED drivers make LED lighting installations even easier compared to bulkier drivers. Even while being small, this series has a high power conversion efficiency rate of 91% ensuring low power consumption. These four fully integra...

All LEDs are  driven electrically before they can emit quality light.  This is one of their basic characteristics which differentiate them from other kinds of light sources.  In this write-up, we’re going to be focusing on the DC drive circuitry for LEDs. In the first place, the battery is a typical DC source. It’s usually used for flashlights. It can as well serve as the output of a converter.  Actually, DC is quite different from AC.  The difference is that DC has much lower voltage than AC.  Hence, the regulations gov...

Fairchild Semiconductor has introduced its LED lighting driver solutions portfolio to include an optimized low-power offering. The FLS0116, FLS3217 and FLS3247 with integrated MOSFET and power factor correction (PFC) are optimally designed for low-power LED applications. With the addition of the integrated power MOSFET, these devices help to minimize board space and overall component count while decreasing design time.Equipped with cycle-by-cycle current limiting and integrated protection features such as over temperature protection (OTP) and under-vo...

The RACV30 is the first of a new series of constant voltage LED drivers, ideal for powering LED strips and LED modules in applications such as cove lighting, signage, back lighting, channel letters, displays or under cabinet lighting. The input voltage range of 90 to 264VAC assures full functionality worldwide. The new drivers provide up to 30 watts and are available with outputs of 12VDC or 24VDC. The output voltages are closely regulated to compensate for varying loads or supply changes (2% max.) RACV30 drivers have active PFC and fully comply with EN6...

Power Integrations has released a reference design kit for a 150 W, 48 V power supply for LED streetlights and other industrial/infrastructure lighting systems. The driver circuit described in RDR-292 is more than 93% efficient at 230 VAC input and above 91% at 110 VAC. The design delivers a system power factor of greater than 0.97, THD of less than 10%, and easily meets EN61000-3-2 C. Designs can be scaled from 75 W to 400 W, using the same platform, simply by choosing different HiperPFS™ (PFC) and HiperLCS™ (LLC) family members and si...

New 30W Constant Current Driver Optimized for Residential and Commercial Lighting Applications Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today unveiled a new dimmable LED driver module optimized for worldwide residential, commercial and industrial light fixtures.
