摘要： Techniques for optimizing the trade-off between minimizing switching losses and minimizing conduction losses in a buck converter. In an aspect, each of a high-side switch and a low-side switch may be implemented as a plurality of parallel-coupled transistors, each transistor having an independently controllable gate voltage, allowing adjustment of the effective transistor size. In response to the target voltage of the buck converter corresponding to a relatively high voltage range, more high-side switch transistors and fewer low-side switch transistors may be selected. Similarly, in response to the target voltage corresponding to a relatively low voltage range, more low-side switch transistors and fewer high-side switch transistors may be selected. In an aspect, the techniques may be applied during a pulse-frequency modulation mode.

摘要： A DC-DC converter transforms a DC input voltage to generate a DC output voltage by complementary switching control of a main switching transistor and a synchronous rectifying transistor. The DC-DC converter includes a soft-start circuit configured to generate a soft-start voltage rising from an initial voltage at start-up of the DC-DC converter; and a control circuit configured to control switching of the main switching transistor and the synchronous rectifying transistor based on the soft-start voltage to perform soft start of the DC-DC converter. The control circuit brings both of the main switching transistor and the synchronous rectifying transistor to an off state while the soft-start voltage is lower than the DC output voltage.
