LTC3631 - 45V, 100mA Synchronous Buck Converter with Only 12uA Quiescent Current

Linear Technology has announced the LTC3631, a 45V input-capable synchronous buck converter that can deliver up to 100mA of continuous output current. It operates from an input voltage range of 4.5V to 45V with transient protection up to 60V, making it ideal for automotive and industrial control loop applications. The LTC3631 utilizes internal synchronous rectification and a programmable peak current mode design to optimize efficiency in lower current applications. It delivers efficiencies as high as 92% and requires only 12uA of quiescent current, maximizing battery run time. Its 3mm x 3mm DFN package (or MSOP-8E) and only three tiny externals provide a highly compact solution footprint for a wide array of general purpose applications.
