LT8333RDD#PBF

LT8333 is a current mode DC/DC converter. 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 spread spectrum frequency modulation for low EMI. Additional features include frequency foldback and programmable soft-start to control inductor current during start-up. It is used in application such as industrial and automotive, telecom, medical diagnostic equipment, portable electronics etc.
