Analog Devices Inc. LT8361 Boost/SEPIC/Inverting Converters

The LT8361 Boost/SEPIC/Inverting Converters operate from an input voltage range of 2.8V to 60V and have a programmable switching frequency from 300kHz to 2MHz. For increased efficiency, a BIAS pin can accept a second input to supply the INTV_CC regulator. An external compensation pin allows optimization of loop bandwidth over a wide range of input and output voltages. The SYNC/MODE pin allows synchronization of the LT8361 to an external clock. In addition, the SYNC/MODE pin can be used to select between burst or pulse-skip modes of operation with or without Spread Spectrum Frequency Modulation for low EMI. In burst-mode operation, the LT8361 consumes as little as 9µA quiescent current in order to maintain over 90% efficiency at very low output currents, while keeping typical output ripple below 15mV.

Available in a thermally enhanced 16-Lead MSOP package, the LT8361 is well-suited for applications with input sources ranging from a single-cell Li-Ion battery to multi-cell battery stacks, automotive inputs, telecom power supplies, and industrial power rails.
