ZMDI Launches Boost LED Driver for High-Brightness LEDs in Low-Voltage Lighting Applications
ZMD AG (ZMDI) announced a new addition to its LED driver family, the ZSLS7025, a step-up (boost) converter, for high-brightness LED lighting. It is well suited for many consumer, industrial and after-market automotive applications. The ZSLS7025 is optimal for driving multiple white LEDs connected in series from a low voltage supply.
The ZSLS7025 has an application input voltage range of 6V to 100V, which supports lighting products using multi-cell batteries or regulated 12V, 24V and 48V power rails. A low-voltage feedback mechanism helps maximize the operating efficiency, and the open-circuit detection protects the application circuit. The output current is programmable via external components, and the ZSLS7025 features pulse-width modulation (PWM), linear and dc voltage dimming. With an adjustable over-voltage protection, the chip and the system operate safely even if the load is not connected. Other features include under-voltage protection and over-temperature protection.
"The ZSLS7025, our second boost converter, complements the advantages of the ZLED7015 by increasing the operating voltage range and the output current capability. The step-up topology of the ZSLS7025 enables applications using strings of multiple high-brightness LEDs while being driven from low-voltage sources," stated Andy Smith, Product Manager at ZMDI. "This is particularly attractive for designers of low-voltage high-brightness lighting products, and the ZSLS7025’s extended application operating voltage and current range provide designers with additional flexibility."

The low supply voltage and constant output current operation make the ZSLS7025 an ideal choice for safety extra-low voltage (SELV) applications or multifaceted reflector (MR16) lamps, frequently found in residential and retail lighting applications. Other key application areas include low-voltage retrofit lighting, replacement tubes, LED backlighting, after-market automotive lighting products, low-voltage general-purpose industrial and consumer applications, as well as signage, outdoor, architectural and building lighting.
The ZSLS7025 is supplied in a RoHS-compliant SOP-8 package, and its operating temperature range is -40 to +85°C (-40 to +185°F).
Opinion: Maximising Synergies between Power Electronics and ICT for improving Energy Efficiency
Samples and a complete evaluation kit are available upon request. For 2,500 pieces, the ZSLS7025 is priced at €0.62/$0.80.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
