15-V, 2.5-A synchronous boost DC/DC converter is offered in a high temperature grade
The LTC3122 is a 3 MHz current-mode, synchronous boost DC/DC converter with integrated output disconnect.
The device’s internal 2.5 A switches deliver output voltages as high as 15 V from an input voltage range of 1.8 V at start-up (0.5 V when running) to 5.5 V, making it ideal for various battery chemistries or standard 3.3 V and 5 V power sources. The LTC3122 can deliver up to 800 mA of continuous output current at 12 V from a 5 V input. Pin-selected Burst Mode operation lowers quiescent current to only 25 µA, providing extended battery run time in handheld applications. The combination of its thermally enhanced MSOP-12 package and a constant switching frequency up to 3 MHz enables the designer to balance printed circuit board solution size with required efficiency.
The H-grade version is specified over an operating junction temperature range of -40°C to +150°C. The electrical specifications are identical to the existing E and I grades. The version of the device is ideal for automotive, industrial and military applications that are subject to high ambient temperatures.
Availability and Pricing
The LTC3122HMSE is available in a 12-lead thermally enhanced MSOP package, priced starting at $2.98 each for 1,000-piece quantities and is available from stock.
