DATASHEET To request the full datasheet, please visit www.intersil.com/products/isl98608 High Efficiency Single Inductor Positive/Negative Power Supply ISL98608IIH Features 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 -5V (default). The ±5V output voltages can be adjusted from ±4.5V up to ±7V with 50mV steps using the I2C interface. • Two outputs: - VP = +5V (default) - VN = -5V (default) • 2.5V to 5.5V input voltage range • ±4.5 to ±7V wide output range • Supports 200mA current between VP and VN The device integrates synchronous rectification MOSFETs for the boost regulator and inverting charge pump, which maximizes conversion efficiency. • >89% efficiency with 12mA load between VP and VN • 18mm2 solution PCB area The ISL98608IIH integrates all compensation and feedback components, which minimizes BOM count and reduces the solution PCB size to 18mm2. • Fully integrated FETs for synchronous rectification 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. • Integrated VP/VN discharge resistors • Integrated compensation and feedback circuits • I2C adjustable output voltages and settings • 1µA shutdown supply current • Programmable turn-on and turn-off sequencing 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. • 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 VIN 2.5V TO 5.5V L1 CIN VIN LXP SCL VBSTCP VBST CVBST CCP CVN -5V LCD PANEL CP SDA ENP PROCESSOR ENN ISL98608IIH CN VN NEGATIVE SUPPLY POSITIVE SUPPLY +5V VSUB VP AGND PGND CVP FIGURE 1.
