LT8362 is a current mode, 2-MHz step-up DC/DC converter with an internal 2A, 60V switch. It operates from an input voltage range of 2.8V to 60V, suitable for applications with input sources ranging from a single-cell Li-Ion battery to automotive and industrial inputs.

The converter 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. It offers over 90% efficiency switching at 2 MHz. Burst Mode operation reduces quiescent current to 9 µA while keeping output ripple below 15 mVP-P. The combination of a 3 x 3 mm DFN or high voltage MSOP-16E package and tiny external components enables a compact footprint while minimizing solution cost.


The LT8362’s 165 mΩ switch is capable of 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, internal soft-start, frequency foldback and programmable soft-start.


The LT8362EDD is available in a 3mm x 3mm DFN-10 package and the LT8362EMSE is available in a high voltage MSOP-16E (4 pins removed for high voltage). Pricing starts at $2.95 (1000).
