5 V to 28 V.
These devices include 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 TPS5433xA family of devices in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaw...
