The LTC3631 synchronous buck converter can deliver up to 100 mA of continuous output current operating from an input voltage of 4.5 to 45 V. Together with 60-V transient protection, these specifications make the device well-suited for automotive and industrial control applications. Internal synchronous rectification and a programmable peak current mode design optimize efficiency in lower-current applications. The converter offers efficiencies up to 92% and draws only 12 µA of quiescent current, maximizing battery run time. A 3- by 3-mm DFN package and the need for only three very small external components minimizes board footprint. The converter’s inherent stability eliminates the need for external compensation, reducing total footprint even further. An MSOP-8E package is also available. The LTC3631 is available with either an adjustable output voltage (down to 0.8 V) or with a fixed 3.3- or 5-V output. Prices for the LTC3631EDD and LTC3631EMS8E start at $2.95 each in quantities of 1000. The LTC3631IDD and LTC3631IMS8E cost $3.39 each in quantities of 1000. All versions are available from stock.
