Description
General part information
LT8342 Series
The LT®8342 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 VINpin 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 Pre- Boost applications.To reduce VOUTquiescent current in the feedback loop, an optional internal resistor divider (≥10MΩ) and two pins select 21 output voltage levels.The LT8342 integrates 40V, 9A power switches, operating at a switching frequency programmable between 300kHz and 3MHz and synchronizable to an external clock. The LT8342 features a programmable output soft-start, output power good flag, and output overvoltage lockout.APPLICATIONSAutomotive and Industrial Power SuppliesGeneral Purpose Step-Up
