Description
LTC3536IDD#TRPBF is a dual synchronous buck regulator IC from Linear Technology (now Analog Devices). It provides two high‑efficiency switching regulators with integrated MOSFETs, allowing you to convert a single input voltage to two programmable low voltages. Each output is set with external feedback resistors and the device includes enable/shutdown, soft‑start, overcurrent protection, and thermal protection for robust operation. The suffixes “IDD#TRPBF” indicate the specific device variant and packaging: TRPBF = Tape‑and‑Reel, lead‑free. For exact pinout, input voltage range, maximum output currents, and voltage limits, consult the LTC3536 datasheet and the product page.
