White LED Driver with Wide PWM Dimming Range
ISL97634
The ISL97634 represents an efficient and highly integrated
PWM boost LED driver that is suitable for LED backlighting in
small size LCD panels. 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 various number of LEDs in series. The ISL97634 is
specified for operation over the -40°C to +85°C ambient
temperature at input voltage from 2.4V to 5.5V.
