The ISL98611 is a high-efficiency display power supply and LED driver for small size displays, such as smart phones. It integrates a boost regulator, LDO, and inverting charge pump that are used to generate regulated positive and negative voltages for display power. It also integrates a boost regulator and 3-channel current sinks for the LED backlight driver. The positive and negative output voltages can be adjusted from ±4. 5V up to ±6V. The ISL98611 extends the battery life of mobile devices by delivering greater than 88% efficiency for the display power function and up to 93% efficiency for the backlight driver when powering 12 LEDs. It reduces the PCB area by integrating the two functions into a single IC and by requiring only eight external components in total. This product drives backlight LEDs with excellent current matching even at very low LED current (±2. 2% down to 1mA and ±2. 8% at 50μA), improving the brightness uniformity of LCD displays. It includes analog, PWM, and hybrid dimming to maximize LED efficiency while eliminating color shift issues. The ISL98611 is offered in a 2. 33x2. 61mm2 WLCSP package and the device is specified for operation across the -40°C to +85°C ambient temperature range.
