nn Small 10-Lead MSOP Package The LT®8608 is a compact, high efficiency, high speed
synchronous monolithic step-down switching regulator
that consumes only 1.7µA of quiescent current. The LT8608
can deliver 1.5A of continuous current. Top and bottom
power switches are included with all necessary circuitry
to minimize the need for external components. Low ripple
Burst Mode operation enables high efficiency down to
very low output currents while keeping the output ripple
below 10mV. A SYNC pin allows synchronization to an...
