Linear – New 2.5A / 15V synchronous boost regulator offers 95% efficiency (LTC3122)Oct 22 2012 - Power [More Power Articles]
A new 3MHz current-mode, synchronous boost DC-DC converter, with integrated output disconnect, has been unveiled by linear technology.
The LTC3122′s internal 2.5A 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 ideal for battery or standard 3.3V and 5V power sources.
The LTC3122 can deliver up to 800mA of continuous output current at 12V from a 5V input. Pin-selected Burst Mode operation lowers quiescent current to only 25µA, providing extended battery run time in handheld applications.
The combination of thermally-enhanced 3mm x 4mm DFN-12 (or MSOP-12) package and a constant switching frequency of up to 3MHz enables the designer to balance PCB solution size with required efficiency, says the company.More news from Linear
