DESCRIPTION
Boost and Single Inductor
Inverting DC/DC Converters with
Optional I2C Programing and OTP
TheLT3582/LT3582-5/LT3582-12aredualDC/DCconverters
featuringpositiveandnegativeoutputsandintegratedfeedback
resistors.TheLT3582,withitsbuilt-inOneTimeProgramming
(OTP), has congurable output settings via the I2C interface,
including output voltage settings, power-up sequencing,
power-downdischarge,andoutputvoltageramprates.LT3582
settings can be changed adaptively in the nal 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
–50mVsteps.TheLT3582-5andLT3582-12arepre-congured
at the factory for ±5V and ±12V outputs respectively, and as
such, don’t require the use of the I2C interface.
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 efciency over a wide load current range. The
LT3582 series is available in a 16-pin 3mm
× 3mm QFN.
