TPS54302DDCR
The TPS54302 is a 3-A synchronous step-down converter operating from a 4.5 V to 28 V input with adjustable output down to 0.6 V. It uses current-mode control with spread-spectrum EMI reduction, 40 uA quiescent current, fixed soft-start and adjustable UVLO. Rated -40 degC to 125 degC, it targets industrial, consumer and wide-VIN power supplies.
