In this training, Oliver discusses how to achieve high light load efficiency with a DC/DC converter via pulse frequency modulation. Further, discover the key device parameters to keep output voltage ripple low and ensure a seamless transition between PFM (pulse frequency modulation) and PWM (pulse width modulation) modes. Finally, learn how to achieve 360nA of device quiescent current under full operation with the TPS62743 buck converter.
