Switching at 2.25 MHz keeps the inductor and output capacitor small — a 2.2 µH inductor and 10 µF ceramic cap are typical for each channel. The synchronous rectifier eliminates the external Schottky diode, saving board area and improving efficiency across the load range. ## Package and board-fit — exposed pad matters Housed in an 8-lead WFDFN with exposed pad (3 mm × 2 mm body, 0.50 mm pitch), the LTC3547EDDB#TRPBF requires a thermal land on the PCB to sink heat from the die. No AEC-Q grade is listed, so this part is not qualified for under-hood automotive use.","metaTitle":"LTC3547EDDB#TRPBF Dual 300mA Buck Regulator, 2.25MHz","metaDescription":"LTC3547EDDB#TRPBF dual 300mA step-down buck converter, 2.5-5.5V input, adjustable output, 8-DFN package.
