Working Principles

The S-8333TCIB-T8T1U operates as a voltage regulator by comparing the feedback voltage (FB) with a reference voltage. It adjusts the duty cycle of an internal switching transistor to maintain the desired output voltage. The overcurrent protection monitors the current flowing through the IC and triggers a shutdown if it exceeds a predefined threshold. Similarly, the thermal shutdown protection activates when the temperature rises above a specified limit, preventing damage to the IC.
