Working Principles

The TNY279GNAU is a switched mode power supply (SMPS) controller that regulates the output voltage by controlling the duty cycle of an internal power MOSFET. It operates in a flyback topology, where energy is stored in an inductor during the switch-on time and transferred to the output during the switch-off time. The controller adjusts the duty cycle based on feedback from the output voltage, maintaining stable and regulated power delivery.
