DESCRIPTION
The
LT
®
8362
is a current mode DC/DC converter with a
60V, 2A switch operating from a 2.8V to 60V input. With
a unique single feedback pin architecture it is capable
of boost, SEPIC or inverting configurations. Burst Mode
operation consumes as low as 9µA quiescent current to
maintain high efficiency at very low output currents, while
keeping typical output ripple below 15mV.
An external compensation pin allows optimization of loop
bandwidth over a wide range of input and output volt-
ages and programmable switching frequencies between
300kHz and 2MHz. A SYNC/MODE pin allows synchroni-
zation to an external clock. It can also be used to select
between burst or pulse-skipping modes of operation with
or without Spread Spectrum Frequency Modulation for
low EMI. For increased efficiency, a BIAS pin can accept
a second input to supply the INTV
CC
regulator. Additional
features include frequency foldback and programmable
soft-start to control inductor current during start-up.
The LT8362 is available in a thermally enhanced 10-lead
3mm
×
3mm DFN package or a thermally enhanced
16-lead MSOP package with four pins removed.
