It takes a 3 V to 20 V input rail and drives a single positive output with up to 90% duty cycle. The controller integrates an enable pin, power-good indicator, and soft-start — the three control signals you actually wire up on a board. The synchronous rectifier means you skip the external Schottky catch diode, saving a component and a bit of board space. ## Lifecycle and sourcing No end-of-life notice, no last-time-buy window to chase. For the BOM line, that means no forced redesign for obsolescence in the foreseeable future.","metaTitle":"TPS40345DRCT Buck Controller, 600kHz, 3V-20V, Active","metaDescription":"TPS40345DRCT step-down PWM buck controller, 600kHz switching, 3V to 20V supply, enable/power good/soft start, 10-VSON package.
