n AEC-Q100 Qualified for Automotive Applications The LT®8610A/LT8610AB series are compact, high efficiency, high speed synchronous monolithic step-down
switching regulators that consume only 2.5µA of quiescent current. Compared to the LT8610, they have higher
maximum output currents of 3.5A and a faster minimum
switch-on time of 30ns. The LT8610A has the same low
ripple burst mode performance of the LT8610, while the …
