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.","metaTitle":"Analog Devices LT3663EDCB#TRPBF Step-Down Regulator, 1.2 A","metaDescription":"Analog Devices LT3663EDCB#TRPBF step-down buck regulator, adjustable output, 1.2 A, 7.5-36 V input, -40°C to 125°C.
