Primary-Side Peak-Current Mode LED Driver for High-Brightness LED Lighting

ZMD AG (ZMDI) has released the newest member of its LED driver family, the ZSLS7031, a primary-side peak-current mode LED driver for high-brightness LED lighting. This new LED driver is well suited for many consumer, commercial and industrial lighting applications, particularly where electrical isolation is required.

“The ZSLS7031, our second line-power LED driver, complements the advantages of our ZLED7001 by adding isolated and exciting new non-isolated applications. The device works at a constant frequency in discontinuous conduction mode to provide constant power to the output. The ZSLS7031 eliminates the need for an opto-coupler or any other type of secondary-side feedback and operates from a wide input voltage range of 85Vac to 265Vac,” said Erhard Muesch, System Architect at ZMDI.

Key features include: Power factor correction to > 0.95; Wide input voltage range: 85V to 265Vac; Isolated and non-isolated applications; Internal over-temperature, over-voltage and primary side open connection protection; and operating temperature:-45°C to +105°C.

The ZSLS7031 is in full production and supplied in a RoHS-compliant MSOP8 package. Samples and kits are available upon request from ZMDI or through one of its distribution partners. For 2,500 pieces, the ZSLS7031 is priced at EUR 0,52 or USD 0.73 per unit.
