FN6264.3

White LED Driver with Wide PWM

Dimming Range

Features

• Drives Up to 7 LEDs in Series (3.5V/20mA type)

• OVP (14V, 18V, and 26V for 3, 4 and 7 LEDs Applications)

• PWM Dimming Control From DC to 32kHz

• Output Disconnect Switch

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 7 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.

• 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

• Internally Compensated

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 7 LEDs (3.5V/20mA type)

backlight applications respectively. The ISL97634 is

specified for operation over the -40°C to +85°C ambient

temperature at input voltage from 2.4V to 5.5V.

• 8 Ld TDFN (2mmx3mm)

• Pb-Free (RoHS Compliant)

Applications

• LED Backlighting for:

- Cell phones

Pinout

- Smartphones

- MP3
