詳細說明
For applications requiring low output voltage ripple, the TPS62067DSGT can be forced into fixed frequency PWM mode by pulling the MODE pin high. Additionally, this converter features an open drain power good output for enhanced performance in low noise applications. In shutdown mode, the TPS62067DSGT consumes less than 1µA of current, with an internal circuit that discharges the output capacitor to further minimize power consumption
