In most major economies, electromagnetic compliance laws govern how much electrical energy an LED lamp can emit. In fact, just this month there has been a change to European EMI requirements with the EN55015:2013 standard coming into effect in the near future. Under EN 55015:2013, manufacturers are required to measure ELV LED lamps on a 50Hz or 60Hz wire wound transformer, unless they state clearly that it cannot be used with such wire wound transformers - a transformer type which is still very common in Europe. Since ongoing research is a crucial part of the product development philosophy at Indice, we investigated how a cross segment of LED MR16 lamps performed to various global compliance standards. Our testing team found that many of the major brands do not comply with emissions requirements on commonly available power transformers. For manufacturers, this means a major compliance challenge and potentially serious liability issues. Above chart: Indice LED MR16 drivers are EMI compliant on standard halogen transformers (electronic / magnetic) and meet new requirements of EN55015 / CISPR15 and FCC. Indice's MR16 LED drivers meet the EMI compliance requirements of all major regions. Our fast-switching, smart drivers smoothly draw power from transformers without requiring an EMI filter, an additional circuit part that adds cost and size to your lamp design. EMI filters typically consist of inductors and capacitor networks to remove additional electrical noise. However Indice avoids usage of EMI filters due to it's unique Continuous SigmaTM signal encoding method. Continuous SigmaTM is incredibly quiet - no noise, no EMI filter. Are your LED lamps compliant with global EMI requirements?

Fast switching speeds mean smaller drivers. With smaller drivers, you'll have more room for the LED optics. Develop the products you really want to, without compromise. Indice's MR16 LED drivers are some of the smallest available on the market today and we've achieved this through incredibly fast switching speeds. How does this help you design better products? In most cases, LED drivers which are capable of delivering the functionality you need, such as flicker-free dimming and uniform light output, take up a lot space inside the mechanical housing, limiting your ability and flexibility to design the optics you want. Not so with Indice's drivers. Not only do Indice drivers have industry-leading switching speeds, but they also boast low line noise, which means EMI filters are now a thing of the past.

Enhance ZVS with Predictive Lossless Switching to make smaller, cheaper and more efficient power supplies
Indice Semiconductor has developed Predictive Lossless SwitchingTM, a highly efficient and low EMI controller for use with traditional Zero Voltage Switching. Manufacturers using ICs with Predictive Lossless SwitchingTM (PLS) can benefit from all the advantages of Zero Voltage Switching (ZVS) but without the inherent limitations, to produce smaller, more compact, more efficient and cheaper power systems. ZVS has had limited use in high end power supply systems since the 1980s, allowing for operation at higher frequencies without the efficiency losses suffered due to switching. However, it has major limitations to its potential and effectiveness, which have prevented it from being utilized on a large scale. The main drawback of ZVS is that it typically only allows for static control over timing of switching devices, such as dead times, active snubbers, or active resonant commutated poles (ARCP), which limits operation to narrow load bands. Using Indice’s PLSTM controller, switching speed is increased to more than five times faster than that of a hard-switching system, and maintains perfect ZVS over the entire power range. This is because, as the name suggests, PLSTM is predictive, ensuring minimal losses by predicting and adjusting the sequence of switching events of the power circuit. In fact, PLSTM reduces switching losses of half or full bridges by 80%, in insulated-gate bipolar transistors (IGBTs), gallium nitrade (GaN), silicon MOSFETs and silicon carbide (SiC) MOSFETs. With PLSTM, IGBTs can switch at SiC and GaN hard-switching frequencies without the risk or the cost. When combined with wide bandgap devices, PLSTM can exceed megahertz frequencies. PLSTM also reduces losses in self-resonant topologies such as LLC and push-pull systems, by optimising dead time over full input voltage and power range, raising CEC efficiency. In contrast with traditional hard [...]
Indice Semiconductor's long-awaited, next generation "G3" suite of highly efficient, ultra-compatible MR16 LED Driver ICs is here. Having already shipped more than a million LED chips, Indice has built on this success and deep understanding of the LED lighting industry to develop this new and improved range of MR16 LED Driver ICs. Packages have been developed for different budgets and different technical requirements, but all ICs include Indice's signature Active Temperature Management with an adjustable temperature set point. Also typical of Indice Semiconductor technology is the high power density of the "G3" MR16 LED Driver IC, which enables manufacturers to develop more powerful and efficient LED lamps with compact mechanical housing. Each package also benefits from a low part count and industry-leading compatibility with transformer infrastructure. Some packages also feature flicker-free, deep dimming (from 100% - 0% light). IN0312 features inductor-less current regulation (ICR), which enables smooth dimming even on normally difficult transformer and dimmer combinations. The "G3" ICs are ideally suited to MR16, AR111, low voltage outdoor, marine and automotive LED lighting applications.

By Mike Rogoway for the Oregonian Picture this: You're settling in for a romantic meal, uncorking the wine and dimming the lights. Instead of getting that warm mood lighting you expect, though, you get feverish flickering – more suited to a dance floor than an intimate evening. Those energy-efficient LED lights proliferating on store shelves may fit into the regular sockets, but they don't work like the old bulbs. There's a computer chip inside each one regulating how it uses electricity, and some of those chips go haywire when the lights go down. A Tualatin startup has a solution, a tiny computer chip that packs in technology to work with a variety of lighting systems, from dining rooms to big office arrays. Indice Semiconductor says it's already shipped more than a million of its chips. Read the full article on OregonLive here.

We had an amazing time at last week's International Consumer Electronics Show. We saw were so many incredible products there, and lots of possible applications for Indice's ADC and DAC technology. Of course, we spent a bit of time with the Rare Audio team to celebrate the selection of its Element 4.1 car audio amplifier as a 2015 CES Innovation Awards Honoree. The amplifier features Indice Semiconductor components, including an amplifier module and a power supply unit. Indice’s electrolytic capacitor-free amplifier module ensures the Element 4.1 has a slimline, modern look, while improving the reliability and lifespan of the unit. In keeping with our high standards of audio quality, 350WRMS @ 1% THD into 4 Ω, 700WRMS into 2Ω mean the Element 4.1 amplifier has incredible high fidelity sound, with half a horse power per speaker. An SNR of >108dB ensures no audible hiss, even when the car engine is turned off. We also met with some interesting people to talk about our Blade power amplifier module, which has an impressive high-resolution frequency response of >50kHz. The Blade delivers uncompromising control of speakers with excellent attack, fade and phase response, and has an incredible 114dB SNR and THD <0.003. This is only possible with our proprietary Continuous SigmaTM encoding with direct drive technology. When we weren't talking about amplifiers, we did manage to step out onto the show floor to explore some of the other wonders of CES. Are guys in the Indice innovations lab love 3D printing, and a couple of our engineers have built their own, so naturally we checked out the 3D printing section of the show. It is well documented that engineers love pizza, so it should come as no surprise that this was [...]
