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 confi gurable 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 25mV steps. The negative output voltage can
be set between –1.2V and –13.95V in –50mV steps. The LT3582-5 and LT3582-12 are pre-confi gured at the factory for ±5V and ±12V outputs respectively.
