Description

The TPS54262 is a step-down switch-mode power supply with a voltage supervisor and an integrated NMOS switching FET. 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. The device also features low-power mode operation under light load conditions which reduces the supply current to 50 µA (typical). By pulling the EN pin low, the supply shutdown current is reduced to 1 µA (typical).

An open drain reset signal indicates when the nominal output drops below the reset threshold set by an external resistor divider network. The output voltage start up ramp is controlled by a soft start capacitor.
