100mA synchronous buck converter offers 150V input capability
The LTC3639 from Linear Technology is a 150V input-capable synchronous buck converter designed to deliver up to 100mA of continuous output current.

The module operates from an input voltage range of 4.5 to 150V, eliminating the need for an external transient suspension device.
It utilises internal synchronous rectification and a programmable peak current mode design to optimise efficiency over a range of output currents.
Linear claims the buck converter delivers efficiencies up to 92% and requires only 12µA of quiescent current, maximising battery run time and eliminating thermal issues.
The device is offered in a thermally enhanced MSOP package and is targeted at always-on battery powered applications.
