ZMD AG Introduced Boost converter

Published:2011/12/22 1:49:00 Author:Amy From:SeekIC

ZMD AG announced its first step-up converter with integrated 35 V power switch for high brightness LEDs. The ZLED7015 can drive devices that require a constant voltage and the wide input voltage range of 6V to 30V supports applications with input voltage from multi-cell batteries or regulated 12V and 24V power rails. A low voltage feedback mechanism helps maximize the operating efficiency and the device’s soft-start function and open circuit detection protects the application circuit.

The ZLED7015 is an ideal choice for safety extra-low voltage (SELV) applications and multifaceted reflector (MR16) lamps, frequently found in residential and retail lighting applications. The device also can be used in low voltage retrofit lighting, replacement tubes, LED backlighting, aftermarket automotive lighting products, low voltage general purpose industrial and consumer applications, as well as signage, outdoor, architectural and building lighting.

The ZLED7015 is ideal for customers using 6-30V supply to drive multiple high brightness LEDs. The device includes an integrated power switch to minimize system cost and reduce component count for size-optimized applications. The output current is programmable and features PWM, Linear and DC voltage dimming.

The ZLED7015 operates with a switching frequency of 1MHz. A low 0.3V feedback voltage minimizes power loss in the current setting resistor for better efficiency. A built-in soft start circuit reduces the inrush current during start-up and extends the LEDs lifetime. The operating temperature range is -40°C to 85°C. The ZLED7015 is in a MSOP-10 package and is RoHS compliant.
