ZMDI, a Global Semiconductor Company, Launches the ZSLS7025, a High-Efficiency Boost LED Driver for High-Brightness LEDs in Low-Voltage Lighting Applications
DRESDEN, Germany, July 2, 2012 /PRNewswire/ – ZMD AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling
energy-efficient solutions, today 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
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.
-- Wide input range of 6 VDC to 100 VDC -- High efficiency up to 95% -- Open-circuit detection protects against high currents -- Inherently stable control scheme requires no additional loop compensation -- Small form-factor package -- Ideal for low-voltage retrofit lighting
The ZSLS7025 is supplied in a RoHS-compliant SOP-8 package, and its
operating temperature range is -40°C to +85°C (-40°F to +185°F).
Samples and a complete evaluation kit are available upon request. For
2,500 pieces, the ZSLS7025 is priced at EUR0.62/$0.80.
