Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

I claim as my invention: 1. A DC-DC Buck circuit, comprising: a DC input terminal; a DC output terminal; a ground terminal; an inductor between the DC input terminal and the DC output terminal; a capacitor between the DC output terminal and the ground terminal; a sampling resistor between the inductor and the DC output terminal; a PWM control chip, comprising at least one driver pin that supplies a PWM control signal and said PWM control chip further comprising a BOOT…
