描述
The ISL97632 is 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 an integrated Schottky diode, overvoltage protection (OVP), and dynamic digital dimming capability, the ISL97632 provides a simple, reliable, and flexible solution to the backlight designers. The kit is made up of an ISL97632IRTZ-EVALZ evaluation board connected with a USB adapter board that can be programmed by a PC running Windows XP.
