Additional Details

The ISL97698IIZ-T typically operates from a wide input voltage range. The integrated boost converter efficiently steps up the input voltage to the level required by the LED strings. The current sinks precisely regulate the current flowing through each LED string, ensuring consistent brightness and color. The PWM dimming control allows for adjusting the brightness of the display by varying the duty cycle of the PWM signal. The device incorporates various protection features to safeguard against overvoltage, overcurrent, overtemperature, and short-circuit conditions. The ISL97698IIZ-T is available in a small form factor package, making it suitable for compact designs. The switching frequency is optimized for high efficiency and minimal EMI. The device is RoHS compliant.
