Overview: DATASHEET ISL98608
High Efficiency Power Supply for Small Size Displays FN8711 Rev.1.00 Mar 29, 2017 The ISL98608 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: +5.5V (default) and -5.5V (default). The ±5.5V 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.
ISL98608 integrates all compensation and feedback components, which minimizes BOM count and reduces the solution PCB size to 18mm2.
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.
The ISL98608 is offered in a 1.744mm x1.744mm WLCSP package, and the device is specified for operation across the -40°C to +85°C ambient temperature range.
