March 8, 2013 High Efficiency Power Supply for Small Size Displays Features The ISL98607 is a high efficiency power supply for small size
displays, like smart phones, requiring В±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 В±5V output voltages can be adjusted up to
В±5.7V with 50mV steps using the I2C interface. Two outputs:
-VP = +5.0V (default)
-VN = -5.0V (default) 2.8V to 4.4V Input voltage range The device integrates synchronous rectification MOSFETs for
the boost regulator and inverting charge pump, which
maximizes conversion efficiency. >85.5% Efficiency with 12mA load between VP and VN 21mm2 Solution PCB area ISL98607 integrates all compensation and feedback
components, which minimizes BOM count and reduces the
solution PCB size to 21mm2. Fully integrated FETs for synchronous rectification 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. Integrated VP/VN discharge resistors The ISL98607 is offered in a 1.82x2.15mm2 WLCSP package,
and the device is specified for operation over the
-40В°C to +85В°C ambient temperature range. 1.82x2.15mm, 4x5 array WLCSP with 0.4mm pitch Integrated compensation and feedback circuits I2C adjustable output voltages and settings 1ВµA shutdown supply current Pb-Free (RoHS compliant) Applications TFT-LCD Smart phone displays Small size/handheld displays Typical Application
