ISL98607

High Efficiency Power Supply for Small Size Displays

Datasheet

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.

The ISL98607 integrates synchronous rectification

MOSFETs for the boost regulator and inverting

charge pump, which maximizes conversion efficiency.

The ISL98607 integrates all compensation and

feedback components, which minimizes BOM count

and reduces the solution PCB size to 21mm2.

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.

The ISL98607 is offered in the 1.82x2.15mm WLCSP

and 20 Ld 3x4mm TQFN packages, and the device is

specified for operation across the -40°C to +85°C

ambient temperature range.
