Switching frequency is programmable from 200 kHz to 2.2 MHz via a single resistor. At the low end the efficiency peaks because switching losses drop; at the high end the inductor shrinks to a 0603 or 0805 footprint. ## Package and thermal — 10-DFN with exposed pad A 4-layer board with a solid thermal via array under the DFN keeps the junction below the derating threshold. The package is supplied on tape and reel (cut tape option available), standard for pick-and-place. The 0.5 mm pitch and 3 mm × 2 mm body mean the layout is straightforward — two inner signal layers can fan out without micro-vias.","metaTitle":"LT8618IDDB#TRMPBF Analog Devices Buck Regulator, 100mA, 60V","metaDescription":"Analog Devices LT8618IDDB#TRMPBF step-down buck regulator, 100mA output, 3.4V-60V input, 200kHz-2.2MHz.
