Active production — sourcing through standard channels
The LT3470AEDDB#TRPBF: It is ROHS3 compliant, so it meets the current EU restriction on hazardous substances for new equipment placed on the market.
250 mA step-down with 40 V input ceiling
This is a non-synchronous buck regulator with a single adjustable output, delivering up to 250 mA continuous current from a 4 V to 40 V input rail. The output voltage is adjustable from a minimum of 1.25 V up to 16 V, set by an external resistor divider — the 1.25 V reference is the feedback threshold, not a fixed output.
8-DFN exposed pad — thermal and layout checklist
The 8-WFDFN package with exposed pad (3 mm × 2 mm body) requires a thermal land on the PCB to conduct heat from the die to the board — without a proper via array under the pad, the junction temperature rises above the 85°C ambient limit at full load.
