White LED Driver with Wide PWM Dimming Range

ISL97634

Features

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.

•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

• Output Disconnect Switch

• Integrated Schottky Diode

• 2.4V to 5.5V Input

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.

• 85% Efficiency

• 1.4MHz Switching Frequency Allows Small LC

• 1µA Shutdown Current

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.

• Internally Compensated

• 8 Ld TDFN (2mmx3mm)

• Pb-Free (RoHS Compliant)

Applications

• LED Backlighting for:

- Cell phones
