Texas Instruments TPS54335ADRCT TPS54335ADRCT DC-DC Switching Buck Step Down Regulator Adjustable 4.5V-28Vin 800mV-25Vout 3Aout VSON-10

The TPS54335ADRCT is a 3A Synchronous Step-down Converter with Eco-mode�. This device includes an integrated low-side switching FET that eliminates the need for an external diode which reduces component count. Efficiency is maximized through the integrated 128 and 84mR MOSFETs, low IQ and pulse skipping at light loads. Using the enable pin, the shutdown supply current is reduced to 2µA. This step-down (buck) converter provides accurate regulation for a variety of loads with a well-regulated voltage reference that is 1.5% over-temperature. Cycle-by-cycle current limiting on the high-side MOSFET protects the TPS54335A device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. A low-side sinking current-limit turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection is triggered if the over-current condition continues for longer than the preset time.
