RD-169: 30mA @ 21V Max, 8 ~ 16 Vin

Manufacturer: Texas Instruments

The reference design, with National Semiconductor’s LM3431 three-channel, constant-current LED driver, uses two strings of six series-connected LEDs at a current of 30 mA per string. Each LED has a forward voltage drop of about 3.5V, making the total voltage across each string between 21V and 27V. With a 12V power source, the LM3431 is configured as a boost converter to generate this 21V to 27V o…
