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 two output rails for the display power: +5V (default) and -5V (default). It also integrates a boost regulator and 3-channel current sinks for the LED backlight driver. The ±5V 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 PCB area by integrating the two functions into a single IC and by requiring only 8 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 over the -40°C to +85°C ambient temperature range.
