Description

General part information

LT3663 Series

The LT3663 is a current mode step-down switching regulator with programmable output current limit. The current limit accurately controls the system power dissipation and reduces the size of the power path components.The wide operating input voltage range of 7.5V to 36V (60V transient) suits the LT3663 to a variety of input sources, including unregulated 12V wall adapters, 24V industrial supplies, and automotive power.The LT3663 includes a low current shutdown mode, input overvoltage and undervoltage lockout, and thermal shutdown. Internal compensation and boost diode minimize the number of external exponents. 3.3V and 5V fixed output voltage versions are available.The LT3663 is available in 8-lead DFN and MSOP packages with exposed pads for low thermal resistance.ApplicationsDistributed Supply RegulationAutomotive Battery RegulationIndustrial SuppliesWall Transformer Regulation
