ZMD AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling energy-efficient solutions, announces a new addition to its LED driver family, the ZSLS7025. As a global supplier of analog and mixed-signal solutions for automotive, industrial, medical, information technology and consumer applications, ZMDI introduces 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 makes 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.
For over 50 years, ZMDI has been globally headquartered in Dresden, Germany. With over 300 employees worldwide, ZMDI serves its customers with sales offices and design centers throughout Germany, Bulgaria, France, Ireland, Italy, Japan, Korea, Taiwan, United Kingdom and the United States.
