Single-stage flyback controllers from Infineon shape up smart LED lighting

Thu, Jul 22, 2021

Three single-stage flyback LED controllers for constant output voltages have been introduced by Infineon, in anticipation of increased demand for dimmable and intelligent LED systems.

The ICL8800, ICL8810 and ICL8820 single-stage flyback LED controllers meet performance requirements for LED lighting applications, such as LED drivers and luminaires up to 125W, smart lighting and emergency luminaires. The ICs can also be used in adapters and chargers, flat TVs as well as PCs and monitors up to 125W.

The three IC versions offer benchmarking performance for power factor correction and total harmonic distortion at full load and low load conditions, says Infineon. They are optimised as secondary side regulated (SSR) constant voltage (CV) output flyback controllers and are also suitable for primary side regulation (PSR). Critical conduction mode (CCM) and quasi-resonant mode (QRM) with smart valley hopping ensure low EMI without compromising light quality, says the company.

ICL8800 is the basic model, ICL8810 has an integrated burst mode that allows a very low standby power consumption of less than 100mW and flicker-free deep dimming down to 0.1 per cent. This makes the ICL8810 suitable for smart lighting applications in connection with microcontrollers. The ICL8820 is additionally equipped with an integrated DC-input jitter function to improve EMI performance and supports the fulfilment of EMI requirements in DC operation. The ICL8820 model is claimed to ease EMI certification in the design of emergency lighting LED driver applications without additional circuitry.

The ICL88xx family offers an external start-up circuit control signal with a set of protection features, including a power limitation and secondary side over-voltage protection. The ICs require a minimum number of external components, claims Infineon.

The gate driver current enables designs up to 125W with MOSFETs. System performance and efficiency can be further optimised using Infineon’s CoolMOS P7 power MOSFETs.

All three single-stage flyback LED controller variants are available in PG-DSO-8 packages and are available for order now.

Cincoze offers series of sunlight-readable industrial panel PCs

Tue, May 04, 2021

For comfortable, convenient smart cities, Tawianese manufacturer Cincoze believes that human machine interfaces (HMIs), sensors, embedded computers, networks, and artificial intelligence data analysis are all technologies which will provide the tools to assess public infrastructure needs.

It has produced a range of outdoor kiosks, the Crystal line, which includes industrial panel PCs with sunlight-readable displays. The modular design is available in a selection of sizes. The sunlight-readable display models afford bright daylight viewing and are strong enough to withstand the challenges of an outdoor environment, says Cincoze. The panel PCs are suitable for outdoor kiosk use in transport kiosks, automatic ticket and other vending machines, public information displays and smart mailboxes.

The Cincoze sunlight-readable panel PC series uses Cincoze’s patented Convertible Display System (CDS) modular design to combine an industrial touch display and an industrial embedded computer module. The result, says the company is an easy-maintenance, easy-upgrade, and future-proof panel PC.

The embedded system component offers various options including, Intel Atom, Pentium, and Core i3/i5 CPUs, up to 64Gbyte of memory, and two 2.5-inch hard disk drives or solid state drives, selectable to match system performance needs.

Display options are from eight to 21.5-inches with projective capacitive (PCAP) touch displays, and high-brightness 1600 nits backlight for visibility even outdoors and in sunlight.

Specific I/O requirements so Cincoze offers the panel PCs with the most commonly needed I/O connections, including USB 3.0, COM, and GbE LAN, to connect to devices like barcode readers, cameras, and card readers. For specialised applications, there is an M.2 E key and two full-size mini-PCIe slots for wireless connectivity modules or any of Cincoze’s mini-PCIe expansion card (MEC) modules for additional COM, USB, and LAN ports.

To ensure uninterrupted operation, the sunlight-readable panel PCs can withstand a temperature range of -20 to +70 degrees C. The front panel is waterproof and dustproof with an IP65 rating. The super-hard 7H touch surface is scratch-resistant and can withstand heavy impacts, says Cincoze.

Relec introduces round TFT displays for outdoors and commerce

Fri, Apr 30, 2021

Round TFT and projected capacitive (PCAP) displays from FutureLabs are now available from Relec Electronics. The 9.5-inch round FLR-0959MLV0PCFA1 by FutureLabs has an active display area of 240mm and resolution of 1540 x 1540 with 1000 CD/M2 brightness.

The round display is suitable for harsh environments and outdoor use, for example in high ambient lighting areas in marine sonar and radar systems. The wide operating temperature range of -30 to +85 degrees C makes it suitable for automotive and industrial display panels.

The round TFT display is available from Relec Electronics with RockTouch’s PCAP touch panels and I2C digital control. It is suitable for commercial use in retail, advertising and information systems in public transportation, museums, building receptions and other municipal areas.

The displays are designed to be easily integrated by the end-user. A variety of options for a bespoke display are also offered. In addition to customised cover glass graphics, Relec offers a choice of apertures for LEDs and USB ports and capacitive switches which can be fitted behind the glass to meet an application’s specific requirements.

Display specialist Relec offers a wide selection of touch panels suitable for applications from commercial grade to automotive and military. Included in the portfolio are touch panels with noise immunity up to 50V/m, suitable for mission-critical applications in medical, automotive and avionic markets.

For commercial applications, PCAP touch panels are durable and offer an easy to use, responsive touch input for retail ordering, information or arcade games, advises Relec.

Relec Electronics carries stock of all standard modules and accessories for next day delivery and has a team of dedicated engineers which can support customers throughout the design process.

Specialist Relec Electronics has a proud 40 year history in the displays’ business. It is able to listen, advise and recommend the best products sourced from a wide range of display technologies.
