Description
The ISL98608 and ISL98608IIH are high efficiency power supplies for small size displays, such as smart phones and tablets requiring ±supply rails. They integrate a boost regulator, LDO, and inverting charge pump that are used to generate two output rails: +5. 5V and -5. 5V (ISL98608) and +5V and -5V (ISL98608IIH). The output voltages can be adjusted from ±4. 5V up to ±7V with 50mV steps using the I2C interface. The devices integrate synchronous rectification MOSFETs for the boost regulator and inverting charge pump, which maximizes conversion efficiency. The ISL98608 and ISL98608IIH integrate 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 devices ideal for use in single cell Li-ion battery operated applications. The ISL98608 and ISL98608IIH are offered in a 1. 744mmx1. 744mm WLCSP package, and the devices are specified for operation across the -40°C to +85°C ambient temperature range.
