ANALOG DEVICES LT8342RV#TRMPBF DC-DC Switching Synchronous Boost Regulator, Programmable, 2.8 to 40V in, 36V/9A Out, LQFN-EP-24

LT8342RV#TRMPBF is a low IQ, synchronous step-up DC/DC converter. It features a Silent Switcher architecture and optional spread spectrum frequency modulation to minimize electromagnetic interference (EMI) emissions while delivering high efficiencies at high switching frequencies. Output short circuit protection and inrush current reduction are optional. The wide input/output voltage range, low VIN pin quiescent current in Burst Mode operation, and 100% duty cycle capability for the synchronous MOSFET in PassThru operation (VIN ? VOUT) make the LT8342 ideally suited for general-purpose step-up and automotive PreBoost applications. To reduce VOUT quiescent current in the feedback loop, an optional internal resistor divider (?10Mohm) and two pins select 21 output voltage levels. Applications include automotive and industrial power supplies, general purpose step-up.
