The TPS54362 is a step down switch mode power supply with voltage supervisor. Integrated
input voltage line feed forward topology improves line transient regulation of the voltage mode
buck regulator. The regulator has a cycle-by cycle current limit. A pulse skip mode operation under
no load reduces the supply current to 65 µA. Using the enable pin, the supply shutdown current is
reduced to 1 µA.
An open drain reset signal indicates when the nominal output drops below the threshold
set by an external resistor divider network. The output voltage start up ramp is controlled by a
soft start capacitor. There is an internal undervoltage shut down which is activated when the input
supply ramps down to 2.6 V.
