FN9239.3
LED Driver with 1-Wire Dimming
The ISL97632 represents an efficient and highly integrated
PWM boost LED driver that is suitable for 1.8” to 3.5” LCDs
that employ 2 to 7 white LEDs for backlighting. With
integrated Schottky diode, OVP, and dynamic digital
dimming capability, the ISL97632 provides a simple, reliable,
and flexible solution to the backlight designers.
The ISL97632 features a simple 1-Wire digital interface that
provides a 5-bit dimming control. The dimming signal adjusts
the FB voltage and therefore the LED brightness in a DC
manner in 32 linear steps. An EN pin can be used to provide
a zero brightness setting or shutdown power saving function.
The ISL97632 is available in the 8 Ld TDFN (2mmx3mm)
package. There are 14V, 18V, and 26V OVP options that are
suitable for 3, 4, and 7 LEDs (3.5V/20mA type) backlight
applications respectively. The ISL97632 is specified for
operation over the -40°C to +85°C ambient temperature at
input voltage from 2.4V to 5.5V.

NOTE: These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is 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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
