LT8362IDD#PBF

LT®8362 is a current mode DC/DC converter with a 60V, 2A 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. 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. Other features include frequency foldback and programmable soft-start to control inductor current during start-up. Typical applications are telecom, medical diagnostic equipment and portable electronics.
