ZLED7320 40V LED-Driver-ICs
ZMD has announced availability of the ZLED7320 40V LED-Driver-IC, which operates at up to 98 per cent efficiency and is designed to help manufacturers within the high-brightness (HB) LED lighting market.
The ZLED7320 is suited to a range of cost- and size-sensitive applications, including retrofit LED lamps, signage, street and traffic lights, spotlights, appliance lighting and all types of general home and office illumination, the company claims.
ZMD has also introduced the ZLED7330, a high-current 40V LED driver with user-selectable switch dimming that is suitable for high-brightness LED lighting applications and the ZLED7002, a dual-channel LED Driver with supply-voltage switchable channel toggling that is suitable for extended-life battery operated portable LED lighting applications.
