New Energy Efficient LED Drivers
Product Announcement from Servoflo Corporation
Servoflo is pleased to announce three new energy efficient LED driver ICs from ZMDI of Germany. The drivers achieve up to 95% efficiency and demonstrate a commitment to green technology.
ZMDI's LED driver portfolio is designed for all types of internal and external lighting applications. The ZLED7000 and ZLED7010 drive single or multiple LEDs from a supply voltage range of 6 to 40 volts, using continuous-mode inductive step-down converters. The ZLED7001 is a peak current mode control LED driver which operates within a wide input range from 8VDC to 450VDC or 110VAC / 220VAC, making it ideal for direct line-powered applications. All three devices have a very small footprint and are highly integrated thus enabling a very low bill of materials (BOM) cost.
The ZLED7000 and the ZLED7010 LED driver both feature an integrated current-switching transistor and require only four external components for a complete driver. Both support wide-range dimming. The ZLED7010 also has integrated LED temperature compensation to ensure that the LED lifetime is maximized. The measured temperature information for the compensation can be cascaded through the ZLED7010 to serve up to 13 LED drivers. Both devices can drive up to 750 mA of LED current, and feature regulation better than 2 mA delivering consistent, flicker-free brightness.
For line-powered applications, the ZLED7001 universal LED driver allows efficient operation of High Brightness (HB) LEDs with voltage sources ranging from 8 VDC to 450 VDC, including rectified 110 VAC / 220 VAC. Direct connection to the power line dramatically reduces the cost and size of LED lamps, and makes it possible to create LED lamps which are direct replacements for conventional incandescent and fluorescent lamps. The ZLED7001 delivers excellent dimming response and can be dimmed using either Pulse-Width-Modulation techniques or via a linear input control pin. A temperature-compensation input can be used to ensure maximum LED lifetime.
For all three devices, full application kits including application notes and an evaluation board are available now. The ZLED7000 comes in a SOT89-5 package, making it ideal for space-constrained applications such as signage or specialty architectural lighting. The ZLED7001 and ZLED7010 are available in a SOP-8 package. All three devices are available in mass production now.
