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.
FEATUREs
• 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
• >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
