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.
Applications
- Digital Still and Video Cameras
- Scanner and Display Systems
- PDA, Cellular Phones and Handheld Computers
- LED Backlight and OLED Display Drivers
- CCD Imager Bias
- General High Voltage Supply Bias
