Abstract:
A constant on-time control switching converter with DC calibration is disclosed. A current flowing into a capacitor of a DC calibration circuit is reduced by introducing a transconductance amplifier and a resistor. Thus, the equivalent capacitance of the capacitor is magnified, which allows the user to integrate a capacitor with smaller capacitance to realize DC calibration.
