• Operating temperature range (-40°C to +85°C) may restrict usage in extreme environments.

Working Principles

XC6121A422MR-G operates by comparing the output voltage with a reference voltage. If the output voltage deviates from the desired value, the internal circuitry adjusts the current flow to maintain a stable output voltage. The overcurrent protection feature monitors the output current and limits it when necessary. In case of excessive temperature, the thermal shutdown mechanism activates, temporarily disabling the device until the temperature returns to a safe range.
