Working Principles

The TOP267KG-TL is a flyback switching regulator that utilizes a power MOSFET to control the energy transfer from the input to the output. It operates in a continuous conduction mode, where energy is stored in the transformer during the switch-on time and transferred to the output during the switch-off time. The feedback pin monitors the output voltage and adjusts the duty cycle of the internal switch to maintain a stable output.
