LT8331IMSE#PBF

LT8331 is a current mode DC/DC converter. Burst Mode operation consumes as low as 6μA quiescent current to maintain high efficiency at very low output currents, while keeping typical output ripple below 20mV. The internally-compensated current mode architecture results in stable operation over a wide range of input and output voltages and programmable switching frequencies between 100KHz to 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. 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 for controlling inductor current during start-up. It is widely used in application such as industrial and automotive, telecom, medical diagnostic equipment, portable electronics etc.
