Abstract
A DC-DC Buck circuit has a DC input terminal, a DC output terminal, a ground terminal, an inductor, a capacitor, a sampling resistor, a PWM control chip and a DrMOS chip. The output of the driver pin of the PWM control chip is unrelated to the voltage between the inductor and the sampling resistor. The DC-DC Buck circuit can produce a larger output voltage while also being compatible with a DrMOS chip.
