DATASHEET ISL98608IIH High Efficiency Single Inductor Positive/Negative Power Supply FN8724 Rev.2.00 Sep 26, 2017 The ISL98608IIH is a high efficiency power supply for small size displays, such as smart phones and tablets requiring ±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 ±5V output voltages can be adjusted from ±4.5V up to ±7V with 50mV steps using the I2C interface. The device integrates synchronous rectification MOSFETs for the boost regulator and inverting charge pump, which maximizes conversion efficiency. The ISL98608IIH integrates all compensation and feedback components, which minimizes BOM count and reduces the solution PCB size to 18mm2.
