DC/DC Converter Packs 4A/60V Switch

Analog Devices offers the Power by Linear™ LT8364, a current-mode, 2-MHz step-up dc/dc converter with an internal 4A/60V switch. It operates from an input voltage range of 2.8V to 60V, and is suitable for applications with input sources ranging from a single-cell Li-Ion battery to multicell battery stacks, automotive inputs, telecom power supplies and industrial power rails.

 

The LT8364 can be configured as either a boost, SEPIC or an inverting converter. Its switching frequency can be programmed between 300 kHz and 2 MHz, enabling designers to minimize external component sizes and avoid critical frequency bands, such as AM radio. It offers over 90% efficiency while switching at 2 MHz. Burst Mode operation reduces quiescent current to 9 μA while keeping output ripple below 15 mVp-p.

North America’s can’t-miss event dedicated to sensors, connectivity, and IoT will take place this June 22-24 in San Jose, CA. Attendees can make connections, collaborate with experts & peers, get insight into emerging technology & trends, and find new approaches to evergreen challenges. Use promo code FE100 for $100 off Conference Passes.

 

The LT8364’s 100 mΩ power switch delivers efficiencies of over 95%. It also offers spread spectrum frequency modulation to minimize EMI concerns. A single feedback pin sets the output voltage whether the output is positive or negative, minimizing pin count. Other features include external synchronization, programmable UVLO, frequency foldback and programmable soft-start.

 

The LT8364EDE is available in a 4 mm x 3 mm DFN-12 package and the LT8364EMSE is available in a high voltage MSOP-16E (4 pins removed for high voltage spacing). Industrial temperature (–40°C to 125°C) versions (LT8364IDE and LT8364IMSE), and high temperature (–40°C to 150°C) versions (LT8364HDE and LT8364HMSE) are also available.

All versions are available from stock. Need more specs? Get a datasheet now.
