LT8364 current mode step-up regulator has 2.8V – 60V input range
The LT8364 current mode, 2MHz step-up DC/DC converter has an internal 4A, 60V switch. [via]
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 device can be configured as either a boost, SEPIC or an inverting converter. Its switching frequency can be programmed between 300kHz and 2MHz, enabling designers to minimize external component sizes and avoid critical frequency bands, such as AM radio.
