ISL98611IIZ-T Description

Short technical summary and product information.

The ISL98611IIZ-T from Intersil is a versatile integrated circuit designed for high-efficiency display power and LED driving in mobile devices such as smartphones. It combines a boost regulator, LDO, and an inverting charge pump to generate adjustable positive and negative voltages for display power, ranging from ±4.5V to ±6V. Additionally, it incorporates a boost regulator and three-channel current sinks for the LED backlight driver.

This device is engineered to extend battery life by achieving over 88% efficiency for display power and up to 93% efficiency for the LED driver. It supports precise current matching for LEDs, ensuring brightness uniformity even at low currents (±2.2% down to 1mA). The ISL98611IIZ-T features analog, PWM, and hybrid dimming capabilities to optimize LED efficiency and prevent color shift issues. Its compact design, requiring only eight external components, helps reduce PCB area.

The ISL98611IIZ-T is supplied in a 2.33x2.61mm WLCSP package and is specified for operation within an ambient temperature range of -40°C to +85°C. It is suitable for TFT-LCD smartphone displays and other small-size handheld display applications.
