.. Features n LT3582/LT3582-5/LT3582-12 I2C Programmable Boost and Single Inductor Inverting DC/DC Converters with OTP DESCRIPTION The LT®3582/LT3582-5/LT3582-12 are dual DC/DC converters featuring positive and negative outputs and integrated feedback resistors. The LT3582, with its built in One Time Programming (OTP), has configurable output settings via the I2C interface, including output voltage settings, power up sequencing, power down discharge, and output voltage ramp rates. LT3582 settings can be changed adaptively in the final product, or set during manufacturing and made permanent using the built in non-volatile OTP memory. The positive output voltage can be set between 3.2V and 12.775V in 25m V steps. The negative output voltage can be set between - 1.2V and - 13.95V in - 50m V steps. The LT3582-5 and LT3582-12 are pre-configured at the factory for ±5V and ±12V outputs respectively. The LT3582 series includes two monolithic converters, one Boost and one Inverting. The Boost converter has an integrated power switch and output disconnect switch. The Inverting converter uses a single inductor topology and includes an integrated power switch. Both Boost and Inverting converters use a novel- - control scheme resulting in low output voltage ripple while allowing for high conversion efficiency over a wide load current range. The LT3582 series is available in a 16-pin 3mm x 3mm QFN. L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
