LT8365 DC/DC Converter

Analog Devices' LT8365 is a high voltage micropower boost and inverting converter

Image of Analog Devices' LT8365 DC/DC ConverterADI's LT8365 is a current mode DC/DC converter with a 1.5 A, 150 V switch operating from a 2.8 V to 60 V input. With a unique single feedback pin architecture, it 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 100 kHz and 500 kHz. 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 INTVCC regulator. 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.
