1.2 A step-down buck with 36 V input ceiling
The LT3663EDCB#TRPBF is a step-down (buck) switching regulator from Analog Devices, delivering an adjustable output from 0.8 V to 6 V at up to 1.2 A continuous current. The input range spans 7.5 V to 36 V, covering common industrial bus rails and automotive battery lines without needing an external pre-regulator.
1.5 MHz switching and thermal performance
No synchronous rectifier is used — the external Schottky diode handles the freewheeling current, which simplifies the layout but adds a diode forward-drop loss at high duty cycles.
Active lifecycle and compliance status
ROHS3 compliant — no exemption-listed substances above the threshold, so it meets the EU RoHS directive for new equipment placed on the market.
