LT3582EUD#PBF

LT3582 is a dual DC/DC converter featuring positive and negative outputs and integrated feedback resistors. This device, 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. Device settings can be changed adaptively in the final product, or set during manufacturing and made permanent using the built in non-volatile OTP memory. This device 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. It is used in application such as AMOLED power, CCD power, general purpose DC/DC conversion etc.
