LT8330
Low IQ Boost/SEPIC/
Inverting Converter
with 1A, 60V Switch
Description
The LT®8330 is a current mode DC/DC converter capable
of generating either positive or negative output voltages
using a single feedback pin. It can be configured as a
boost, SEPIC or inverting converter consuming as low as
6µA of quiescent current. Low ripple Burst Mode opera-
tion maintains high efficiency down to very low output
currents while keeping the output ripple below 15mV in
a typical application. The internally compensated current
mode architecture results in stable operation over a wide
range of input and output voltages. Integrated soft-start
and frequency foldback functions are included to control
inductor current during start-up. The 2MHz operation
combined with small package options, enables low cost,
area efficient solutions.
