Abstract: A real current sense apparatus for a DC-to-DC converter uses a current mirror composed by two JFETs to mirror the output current of the converter to generate a temperature-independent mirror current to further generate a current sense signal. Due to the temperature-independence of the mirror current, the current sense signal is also temperature-independent.
