Introduction
Automotive batteries, industrial power supplies, distributed supplies and wall transformers are all sources of wide-ranging high voltage inputs. The easiest way to step down these sources is with a high voltage monolithic step-down regulator that can directly accept a wide input range and produce a well-regulated output. The LT3493 accepts inputs from 3.6V to 36V and the LT3841 accepts inputs from 3.6V to 34V. Both provide excellent line and load regulation and ...
