TPS54335-2ADRCT Part Information
The TPS54335-2A synchronous converter with an input-voltage range of 4.5 V to 28 V. This device has an integrated low-side switching FET that eliminates the need for an external diode which reduces component count. Efficiency is maximized through the integrated 128mΩ and 84-mΩ MOSFETs, low IQ and pulse skipping at light loads. Using the enable pin, the shutdown supply current is reduced to 2 μA. 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 TPS54335-2A in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. A lowside sinking current-limit turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection is triggered if the overcurrent condition continues for longer than the preset time. Thermal shutdown disables the device when the die temperature exceeds the threshold and enables the device again after the built-in thermal hiccup time.
