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 I
2
C 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-configured
at the factory for ±5V and ±12V outputs respectively, and as
such, don’t require the use of the I
2
C 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 efficiency over a wide load current range. The
LT3582 series is available in a 16-pin 3mm
×
3mm QFN.
