1.5A/15V Synchronous Boost Regulator Offers 95% Efficiency
Linear Technology Corp.

Achieving 95% efficiency, the LTC3121 3-MHz, current-mode synchronous boost dc/dc converter features an integrated output disconnect. Its internal 1.5A switches deliver output voltages as high as 15V from an input voltage range of 1.8V at start-up (0.5V when running) to 5.5V, making it viable for battery or standard 3.3V and 5V power sources. The device delivers up to 400 mA of continuous output current at 12V from a 5V input. Pin-selectable Burst Mode operation lowers quiescent current to 25µA, providing extended battery run time. Additional features include external synchronization, output overvoltage protection, and short-circuit protection. The LTC3121EDE is available from stock in a 12-lead, 3 mm x 4 mm DFN. Pricing starts at $2.33 each/1,000. For more information, visit http://www.linear.com/product/LTC3121
