www.DataSheet4U.com LT3587 High Voltage Monolithic Inverter and Dual Boost DESCRIPTION The LT®3587 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 softstart 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.
