ISL97632
White LED Driver with Digital 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 6 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 single-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 DFN (2mmx3mm)
package. There are 14V, 18V, and 26V OVP options that are
suitable for 3, 4, and 6 LEDs 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.
