Delivering efficiencies as high as 88%, the LTC3638 140V-input buck converter provides up to 250 mA of continuous output current and requires only 12 µA of quiescent current. It operates from an input voltage range of 4V to 140V and employs internal synchronous rectification and a programmable hysteretic-mode design to optimize efficiency over a broad range of output currents. The device is programmable with fixed output voltages of 1.8V, 3.3V, or 5V, or a resistor divider can be used to program outputs from 0.8V to VIN. Pricing for the LTC3638EMSE starts at $3.65 each/1,000. For more information, visit
