Abstract
An apparatus includes a wide range differential pair configured to operate at a low voltage level through reducing bias currents in a startup process of a power converter, and operate at a high voltage level through configuring detected voltages to bias the wide range differential pair, a reference circuit configured to regulate a current flowing through the power converter through the wide range differential pair, and a low voltage circuit configured to convert differential currents generated by the wide range differential pair into a control voltage for regulating the current flowing through the power converter.
