Description

General part information

LT3587 Series

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.ApplicationsDigital Still and Video CamerasScanner and Display SystemsPDA, Cellular Phones and Handheld ComputersLED Backlight and OLED Display DriversCCD Imager BiasGeneral High Voltage Supply Bias
