White LED Driver With PWM Dimming

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