ISL97634 FN6264
Rev 4.00
August 27, 2013 White LED Driver with Wide PWM Dimming Range
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. Features 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. • Output Disconnect Switch •Drives Up to 26V Output
•Integrated over-voltage protection (OVP) of 14V, 18V, and
26V for various number of LEDs in series
• PWM Dimming Control From DC to 32kHz
• Integrated Schottky Diode
• 2.4V to 5.5V Input
• 85% Efficiency
• 1.4MHz Switching Frequency Allows Small LC The ISL97634 is available in the 8 Ld TDFN (2mmx3mm)
package. There are 14V, 18V, and 26V OVP options that are …
