DATASHEET ISL98607IRTZR5622 High-Efficiency Power Supply for Small Size Displays FN8651 Rev.1.00 Jan 9, 2018 The ISL98607IRTZR5622 is a high-efficiency power supply for small size displays, like smart phones, requiring ±supply rails. It integrates a boost regulator, LDO, and inverting charge pump that are used to generate two output rails: +5.5V (default) and -5.5V (default). The output voltages can be adjusted up to ±5.7V 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. ISL98607IRTZR5622 integrates all compensation and feedback components, which minimizes BOM count and reduces the solution PCB size to 21mm2.
