The TPS54162 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 conditons 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. There is an internal undervoltage shut down which is activated when the input supply ramps down to 2.6 V. The device is protected during an overload condition on output by frequency fold back operation, and also has a thermal shutdown protection.
