HB LED Driver Eases Area-Lighting Design

June 13, 2011
Exploiting a unique control method to equalize current between multiple LED strings, the LM3466 linear LED driver promises to simplify the design of high-power, wide-area lighting fixtures.

Exploiting a unique control method to equalize current between multiple LED strings, the LM3466 linear LED driver promises to simplify the design of high-power, wide-area lighting fixtures. The device, plus a few passive components, provides a complete system that drives each LED string from any off-the-shelf AC/DC constant-current power supply. The LM3466 integrates a 70V, 1.5A N-Channel MOSFET and provides an input range of 6V to 70V.  Other features include a fault status output, input under voltage lockout, current limit, and thermal shutdown protection. With production quantities coming in July, pricing for the LM3466 in an eight-pin ePSOP is $1.30 each/1,000. NATIONAL SEMICONDUCTOR CORP., Santa Clara, CA. (800) 272-9959.
