The LT8365 is a current mode DC/DC converter with a 1.5A, 150V 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 100kHz and 500kHz. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between burst or pulse-skipping 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 INTVCCregulator. Additional features include frequency foldback and programmable soft-start to control inductor current during startup.The LT8365 is available in a thermally enhanced 16-lead MSOP package with four pins removed for high voltage pin spacings.APPLICATIONSIndustrial and AutomotiveTelecomMedical Diagnostic EquipmentPortable Electronics
