60V boost DC-DC converter has 2A switch
The LT8362 operates from an input voltage range of 2.8V to 60V 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 with a switching frequency between 300kHz and 2MHz, enabling designers to minimize external component sizes and avoid critical frequency bands, such as AM radio.
It has an efficiency over 90% at 2MHz and the burst mode operation reduces quiescent current to only 9µA while keeping output ripple below 15mVP-P. Spread spectrum frequency modulation minimises EMI effects
The LT8362’s 165mΩ switch provides efficiencies of over 95%. and 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 each for 1,000-piece quantities. Industrial temperature (–40°C to 125°C) versions, the LT8362IDD and the LT8362IMSE and high temperature (–40°C to 150°C) versions, the LT8362HDD and the LT8362HMSE, are available.
