Part Name(s) : LM3466 LM3466MR LM3466MRX Texas-Instruments
Texas Instruments
Description : Smart LINEAR LED Driver for Multi-Channel LED SYSTEMS View

General Description
The LM3466 integrates a LINEAR LED driver for lighting SYSTEMS which consist of multiple LED strings powered by a constant current power supply. It equalizes the current provided by the supply in a pre-set ratio for each active LED string, where an active string is a fully turned on LED string, regardless of the number of strings connected to the supply or the forward voltage of each LED string. If any LED string opens during operation, the LM3466 automatically equalizes the supply current through all of the remaining active LED strings. As a result, the overall brightness of the lighting sys tem is maintained even if some LED strings open during operation.
The LM3466 lighting system is simple to design owing to a proprietary control scheme. To minimize the component count, the LM3466 integrates a 70V, 1.5A N-channel power MOSFET WITH a current limit of 2.06A. To add one more LED string to the system, only a single resistor, a capacitor, and a LM3466 are required. Other supervisory features of the LM3466 include under-voltage lock-out, fault reporting, thermal latch off, and thermal shutdown protection.
The LM3466 consists of only LINEAR circuitry so that the EMI of the application circuit is not deteriorated. The LM3466 light ing system is EMI friendly if the constant current power supply used is complied to EMI standards. The LM3466 is available in the PSOP-8 exposed DAP package.

Features
■ Easy to design and use for lighting SYSTEMS consisting of
   multiple LED strings (support modular design)
■ Automatically equalizes the current of every active LED
   string, even the forward voltage of each string is different
■ Easy to pre-set and fine-tune current ratio among LED
   strings (e.g. color temperature adjustment or CRI
   enhancement)
■ ±1% current accuracy at room temperature and ±1.5% over temperature
■ Maintains constant output power if some strings open
   (inactive) by automatically equalizing the current of
   remaining active LED strings
■ Works WITH a constant current power supply (ac/dc or dc/
   dc), and no communication to/from the constant current
   power supply is required
■ Operates WITH minimum voltage overhead to maximize power efficiency
■ Wide input voltage range from 6V to 70V
■ Fault status output
■ Thermal shutdown
■ Integrated 70V 1.5A MOSFET WITH 2.06A current limit
■ Maximum 70V per LED string, 20 LEDs
LINEAR circuitry does not deteriorate EMI
■ PSOP-8 exposed DAP package

Applications
■ Street lamps
■ Solid state lighting SYSTEMS
