LT8364 Boost/SEPIC/Inverting DC-to-DC Converter

Analog Devices LT8364 is a current mode DC/DC converter with a 60 V, 4 A switch operating from a 2.8 V to 60 V input. This converter has a single feedback pin architecture which is capable of boost, SEPIC, or inverting configurations. Burst Mode® operation consumes as low as 9 μA quiescent current to maintain high efficiency at very low output currents, while keeping typical output ripple below 15 mV. An external compensation pin allows optimization of loop bandwidth over a wide range of input and output voltages and programmable switching frequencies between 300 kHz and 2 MHz. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between burst or pulse-skip modes of operation with or without spread spectrum frequency modulation for low EMI. For increased efficiency, a BIAS pin can accept a second input to supply the INTV_CC regulator. The converter is available in a thermally 12-pin DFN package or a 16-pin MSOP package. The LT8362 is perfect for industrial, automotive, or telecom applications.
