Used in a wide range of applications, including automotive, industrial, and telecommunications power supplies.

Analog Devices announced the release of the new Power by Linear LT8364, a current-mode 2MHz step-up DC/DC converter with a built-in 4A 60V switch.

The LT8364 operates in an input voltage range of 2.8V to 60V and can be used in a wide range of input power applications, from single-cell lithium-ion batteries to multi-cell battery stacks, automotive input power, telecommunications power supplies, and industrial power rails.

The LT8364 can be configured as a boost, SEPIC, or inverting converter. The switching frequency is programmable between 300 kHz and 2 MHz, allowing designers to minimize the size of external components and avoid critical frequency bands such as AM radio.

It provides over 90% efficiency at a switching frequency of 2 MHz. Burst mode operation reduces quiescent current consumption to 9 µA while maintaining output ripple below 15 mVP-P. This product is available in 4 mm x 3 mm DFN or high-voltage MSOP-16E packages and minimizes solution costs while ensuring a very compact footprint when used with small external components.

The LT8364 provides over 95% efficiency with a 100mΩ power switch. It minimizes EMI issues through spread-spectrum frequency modulation. The number of pins can be minimized as the output voltage can be set with a single feedback resistor, regardless of whether the output is positive (+) or negative (-). In addition to this, it supports external synchronization, programmable UVLO (under voltage lockout), frequency foldback, and programmable soft start functions.

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