DATASHEET To request the full datasheet, please visit www.intersil.com/products/isl98607 High Efficiency Power Supply for Small Size Displays ISL98607 Features The ISL98607 is a high efficiency power supply for small size displays, like smart phones, requiring ±supply rails. It integrates 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 up to ±5.7V with 50mV steps using the I2C interface. • Two outputs: - VP = +5.0V (default) - VN = -5.0V (default) The device integrates synchronous rectification MOSFETs for the boost regulator and inverting charge pump, which maximizes conversion efficiency. • 21mm2 Solution PCB area ISL98607 integrates all compensation and feedback components, which minimizes BOM count and reduces the solution PCB size to 21mm2. • I2C adjustable output voltages and settings • 2.8V to 4.4V Input voltage range • >85.5% Efficiency with 12mA load between VP and VN • Fully integrated FETs for synchronous rectification • Integrated compensation and feedback circuits • Integrated VP/VN discharge resistors • 1µA shutdown supply current The input voltage range, high efficiency operation, and also very low shutdown current make the device ideal for use in single cell Li-ion battery operated applications. • 1.82x2.15mm, 4x5 array WLCSP with 0.4mm pitch • Pb-Free (RoHS compliant) The ISL98607 is offered in a 1.82x2.15mm2 WLCSP package, and the device is specified for operation over the -40°C to +85°C ambient temperature range.
