LED Driver with 1-Wire Dimming  
Features  
The ISL97632 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 dynamic digital  
dimming capability, the ISL97632 provides a simple, reliable,  
and flexible solution to the backlight designers.  
• 1-Wire 5-Bit Digital Dimming  
• Drives Up to 7 LEDs in Series (3.5V/20mA type)  
• OVP (14V, 18V and 26V for 3, 4, and 7 LEDs applications)  
• Integrated Schottky Diode  
• 2.4V to 5.5V input  
• 86% Efficiency  
The ISL97632 features a simple 1-Wire digital interface that  
provides a 5-bit dimming control. The dimming signal adjusts  
the FB voltage and therefore the LED brightness in a DC  
manner in 32 linear steps. An EN pin can be used to provide  
a zero brightness setting or shutdown power saving function.  
• 1.4MHz Switching Frequency Allows Small LC  
• Enable for Shutdown Function or Zero Brightness Setting  
• 1µA Shutdown Current  
• Internally Compensated  
The ISL97632 is available in the 8 Ld TDFN (2mmx3mm)  
package. There are 14V, 18V, and 26V OVP options that are  
suitable for 3, 4, and 7 LEDs (3.5V/20mA type) backlight  
applications respectively. The ISL97632 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

NOTE: These Intersil Pb-free plastic packaged products employ special  
Pb-free material sets, molding compounds/die attach materials, and  
100% matte tin plate plus anneal (e3 termination finish, which is RoHS  
compliant and compatible with both SnPb and Pb-free soldering  
operations). Intersil Pb-free products are MSL classified at Pb-free peak  
reflow temperatures that meet or exceed the Pb-free requirements of  
IPC/JEDEC J STD-020.
