Overview

Ideal for CCD, LCD, LED Backlight and OLED Applications
Easy Generation of 15V (50mA), –8V (100mA) and 20V (20mA) from a Li-Ion Cell
V_IN Range: 2.5V to 6V
Wide Output Ranges: Up to 32V for the Boosts and Up to –32V for the Inverter
Output Disconnect for the Boost Channels
Boost3 Allows Voltage Programming and/or Current Programming for a ‘One Wire Current Source’
Overload Fault Protection with Fault I/O Pin Indicator
Combined Soft-Start and Enable Pins
Small 20-Pin 3mm × 3mm QFN Package

The LT3587 provides a one-chip solution for applications requiring two positive and one negative high voltage supplies.The LT3587 input voltage range of 2.5V to 6V makes it ideal for various battery-powered systems.

A single resistor programs each of the three output voltage levels and the output current of Boost3. The intelligent soft-start allows for sequential soft-start of the Boost1 output followed by the negative output with a single capacitor. Internal sequencing circuitry also disables the inverter until the Boost1 output has reached 87% of its final value.

The LT3587 integrates all the power switches, soft-start, and output-disconnect circuits into a small 3mm × 3mm QFN package. This high level of integration combined with small external components makes the LT3587 ideal for space constrained applications.
