TPS54335/6 SWIFT™ Converters
TI's 4.5 to 28 V input, 3 A, synchronous, step-down converter with Eco-mode
Cycle-by-cycle current limiting on the high-side FET protects the TPS54335/6 in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit which turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection will be triggered if the overcurrent condition has persisted for longer than the pre-set time. Thermal hiccup protection disables the part when die temperature exceeds thermal shutdown temperature and enables the part again after the built-in thermal hiccup time.
