LT8331IMSE#PBF Description
The LT®8331 is a current mode DC/DC converter with a 140V, 0.5A switch operating from a 4.5V to 100V input. With a unique single feedback pin architecture,
it is capable of boosting, SEPIC, flyback, or inverting configurations. 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.
