摘要:
A sawtooth wave generating circuit that outputs a sawtooth wave signal after calibration and a switch mode power supply device including the sawtooth wave generating circuit is disclosed. The sawtooth wave generating circuit includes a capacitor, a calibration circuit, a charging circuit, discharging circuit and a control unit. The calibration circuit feedbacks a sawtooth wave signal, generates a plurality of voltage signals based on the sawtooth wave signal, and selects one of the voltage signals to generate a calibration output signal. Therefore, the sawtooth wave generating circuit generates a stable sawtooth wave signal regardless of operating conditions.
