The resistors R1 and R2 are applied to terminals 1 and 8, respectively, of the switched-mode power supply 26. These resistors R1 and R2 are current-limiting resistors and function to control the output power and current. A standard buck regulator may be coupled to terminal 5 of the switched-mode power supply 26. The buck regulator includes a diode D7 and an inductor L1. The diode D7 and inductor L1 provide DC rectification and filtering of the high-frequency switch voltage from the switched-mode power supply 26.
