ISL98608IIH FN8724
Rev.2.00
Sep 26, 2017 High Efficiency Single Inductor Positive/Negative Power Supply Features The ISL98608IIH is a high efficiency power supply for small
size displays, such as smart phones and tablets requiring
В±supply rails. It integrates a boost regulator, LDO, and inverting
charge pump that are used to generate two output rails:
+5V (default) and -6 (default). The В±5V output voltages can be
adjusted from В±4.5V up to В±7V with 50mV steps using the I2C
interface. Two outputs:
-VP = +5V (default)
-VN = -5V (default) 2.5V to 5.5V input voltage range В±4.5 to В±7V wide output range The device integrates synchronous rectification MOSFETs for
the boost regulator and inverting charge pump, which
maximizes conversion efficiency. Supports 200mA current between VP and VN >89% efficiency with 12mA load between VP and VN 18mm2 solution PCB area The ISL98608IIH integrates all compensation and feedback
components, which minimizes BOM count and reduces the
solution PCB size to 18mm2. Fully integrated FETs for synchronous rectification Integrated compensation and feedback circuits The input voltage range, high efficiency operation and very low
shutdown current make the device ideal for use in single cell
Li-ion battery operated applications. I2C adjustable output voltages and settings Integrated VP/VN discharge resistors 1ВµA shutdown supply current The ISL98608IIH is offered in a 1.744mm x1.744mm WLCSP
package, and the device is specified for operation across the
-40В°C to +85В°C ambient temperature range. Programmable turn-on and turn-off sequencing 1.744mm x1.744mm, 4x4 array WLCSP with 0.4mm pitch Applications TFT-LCD smart phone displays Small size/handheld displays Hi-Fi audio amplifier supply Typical Application Circuits
