LED DRVR 7Segment 2.5V/3.3V/5V 8-Pin TDFN EP T/R

The ISL97634 represents an efficient and highly integratedPWM boost LED driver that is suitable for LED backlighting insmall size LCD panels. With integrated Schottky diode, OVP,and wide range of PWM dimming capability, the ISL97634provides a simple, reliable, and flexible solution to thebacklight designers. The ISL97634 features a wide range of PWM dimming controlcapability. It allows dimming frequency as low as DC to 32kHzbeyond audible spectrum. The ISL97634 also features afeedback disconnect switch to prevent the output from beingmodulated by the PWM dimming signal that minimizes systemdisturbance. The ISL97634 is available in the 8 Ld TDFN (2mmx3mm)package. There are 14V, 18V, and 26V OVP options that aresuitable for various number of LEDs in series. The ISL97634 isspecified for operation over the -40°C to +85°C ambienttemperature at input voltage from 2.4V to 5.5V.
