Analog Devices LT8364 | Demoboard DC2716A

Low IQ Boost/SEPIC/Inverting Regulator

Overview

TopologyBoost Converter
Input voltage4.5-20 V
Switching frequency300-2000 kHz
Output 124 V / 1.2 A

Description

The LT®8364 is a current mode DC/DC converter with a 60V, 4A switch operating from a 2.8V to 60V input. With a unique single feedback pin architecture it is capable of boost, SEPIC or inverting configurations. Burst Mode operation consumes as low as 9µA quiescent current to maintain high efficiency at very low output currents, while keeping typical output ripple below 15mV. An external compensation pin allows optimization of loop bandwidth over a wide range of input and output voltages and programmable switching frequencies between 300kHz and 2MHz. 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 INTVCC regulator. Additional features include frequency foldback and programmable soft-start to control inductor current during startup. The LT8364 is available in a thermally enhanced 12-lead 4mm × 3mm DFN package or a thermally enhanced 16-lead MSOP package with four pins removed.
