ISL97634
White LED Driver with Wide PWM
Dimming Range
The ISL97634 represents an efficient and highly integrated
PWM boost LED driver that is suitable for 1.8” to 3.5” LCDs
that employ 2 to 6 white LEDs for backlighting. With
integrated Schottky diode, OVP, and wide range of PWM
dimming capability, the ISL97634 provides a simple, reliable,
and flexible solution to the backlight designers.
The ISL97634 features a wide range of PWM dimming
control capability. It allows dimming frequency as low as DC
to 32kHz beyond audible spectrum. The ISL97634 also
features a feedback disconnect switch to prevent the output
from being modulated by the PWM dimming signal that
minimizes system disturbance.
The ISL97634 is available in the 8 Ld TDFN (2mmx3mm)
package. There are 14V, 18V, and 26V OVP options that are
suitable for 3 LEDS, 4 LEDs, and 6 LEDs backlight
applications respectively. The ISL97634 is specified for
operation over the -40°C to +85°C ambient temperature at
input voltage from 2.4V to 5.5V.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
