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 -40C to +85C ambient temperature at input voltage from 2.4V to 5.5V.
