FN6264.4 Changed the information of "max 7 LED in series" to "up to 26V" for more accuracy.
Page 1:
In first paragraph, changed "PWM boost LED driver that is suitable for 1.8" to 3.5" LCDs that employ 2 to 7 white LEDs for
backlighting." to " PWM boost LED driver that is suitable for LED backlighting in small size LCD panels."
Added “Related Literature”
In “Features”, changed "OVP (14V, 18V, and 26V for 3, 4 and 7 LEDs Applications)" to "Integrated over-voltage protection (OVP)
of 14V, 18V, and 26V for various number of LEDs in series". Changed "Drives Up to 7 LEDs in Series (3.5V/20mA type)" to
"Drives Up to 26V Output"
Ordering Information on page 3
Added OVP Options column.
Updated Pb-free note to new verbiage based on lead finish.
Added note to Min Max column of spec table "Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless
otherwise specified. Temperature limits established by characterization and are not production tested."
Added "Boldface limits apply" verbiage to common conditions of spec table. Bolded applicable specs.
“Overvoltage Protection” on page 7, changed "The maximum numbers of LEDs.." to "The maximum LED current.."
Page 8, Table 1, deleted "MAX NO.OF LEDS" column
Page 9:
Changed section title from "8 LEDs Operation" to “Operation with VOUT above 26V”
In same section, changed first sentence from "For medium size LCDs that need more than 7 low power LEDs for backlighting,
such as a portable media player or automotive navigation panel displays, the voltage range.." to "For LED backlighting
applications that need an output voltage above 26V, the voltage range.."
Figure 17, changed inductance value from "2.2μH" to "10μH or 22μH"
Figure 17, changed figure title from "conceptual 8 LEDs high voltage driver" to "high voltage LED driver using a cascode".
Added “Revision History” and “About Intersil” on page 11.
Page 12:
Updated POD L8.2x3A to most recent rev. Updated format and added recommended land pattern
