Overview
The LT8364IMSE#PBF is a high-performance current mode DC/DC converter manufactured by Analog Devices Inc. This component is designed to operate with a wide input voltage range of 2.8V to 60V and features a 60V, 4A power switch. It is versatile, capable of generating either positive or negative output voltages and can be configured as a boost, SEPIC, or inverting converter using a single feedback pin architecture.
The LT8364 is known for its ultralow quiescent current and low ripple Burst Mode operation, making it highly efficient, especially at light loads. It also includes a BIAS pin to further enhance efficiency by allowing an external voltage source to supply the internal voltage regulator.
This device is available in thermally enhanced packages, including 12-lead DFN and 16-lead MSOP, and is AEC-Q100 qualified for automotive applications.
