Abstract:
Embodiments disclosed herein describe an isolated switched-mode power supply with its output regulated from the primary side, by generating a sensing current using a sensing element coupled to the output of the power supply, and measuring a scaled version of the sensing current which depends on the output voltage, and calculating an estimate voltage representing the output voltage, and regulating the output of the isolated switched-mode power supply based on the estimate voltage.
