DESCRIPTION  
FEATURES  
TheLT®3582/LT3582-5/LT3582-12aredualDC/DCconvert-  
ers featuring positive and negative outputs and integrated  
feedback resistors. The LT3582, with its built in One Time  
Programming (OTP), has configurable output settings via

Output Voltages:  
3.2V to 12.775V and –1.2V to –13.95V (LT3582)  
5V and –5V (LT3582-5)

Digitally Re-Programmable (LT3582) Via I C for:  
Output Voltages  
the I C interface, including output voltage settings, power  
upsequencing,powerdowndischarge,andoutputvoltage  
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  
LT3582-5andLT3582-12arepre-configuredatthefactory  
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 result-  
ing 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.
