1 / 34 page  FN8724 Rev.2.01 Dec 7, 2021 ISL98608IIH High Efficiency Single Inductor Positive/Negative Power Supply DATASHEET FN8724 Rev.2.01 Page 1 of 33 Dec 7, 2021 © 2015 Renesas Electronics 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. 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 ISL98608IIH 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. Features •Two outputs: - VP = +5V (default) - VN = -5V (default) • 2.5V to 5.5V input voltage range • ±4.5 to ±7V wide output range • >89% efficiency with 12mA load between VP and VN • 18mm2 solution PCB area • Fully integrated FETs for synchronous rectification • Integrated compensation and feedback circuits •I2C adjustable output voltages and settings • Integrated VP/VN discharge resistors • 1µA shutdown supply current • 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 FIGURE 1.
