摘要： A DC-DC converter system having at least one DC-DC converter operating in either a PWM mode or a PFM mode is provided. The DC-DC converter system includes a state machine configured to control the switching between the PWM mode and PFM mode. The state machine determines whether an inductor current provided by the DC-DC converter reaches a first specified value for a selective number of clock cycles so switching between the PWM mode and PFM mode is to occur. A pulse generator circuit is connected to the state machine and being configured to provide the appropriate switching period for the PWM mode and the PFM mode at the time of switching. The pulse generator circuit is shared amongst the PWM mode or PFM mode and utilizes a master clock for its operations.

摘要： A synchronous rectifier using only n-channel devices in which the low-side switches are effectively cross-coupled using low-side comparators and the high-side switches perform an accurate zero-voltage-switching (ZVS) comparison. The charging path of each bootstrap domain is completed through the low-side switches, which are each always on for every half-cycle independent of loading. This scheme gives rectifier efficiency gain because a) each bootstrap domain receives maximum charging time, and b) the charging occurs through a switch rather than a diode. Both these factors ensure the bootstrap domain is fully charged, thereby reducing conduction losses through the rectifier switches. Furthermore, settings may be adjusted by software to optimize the resistive and capacitive losses of the rectifier. Using data for die temperature and operating frequency, software can create a feedback loop, dynamically adjusting rectifier settings in order to achieve the best possible efficiency.
摘要翻译： 仅使用n沟道器件的同步整流器，其中低侧开关使用低端比较器和高侧开关有效地交叉耦合，执行精确的零电压切换（ZVS）比较。 每个引导域的充电路径通过低端开关完成，每个开关每个半周期不依赖于负载。 该方案提供整流器效率增益，因为a）每个引导域接收最大充电时间，b）通过开关而不是二极管发生充电。 这两个因素都能确保自举域充满电，从而减少整流开关的导通损耗。 此外，可以通过软件来调整设置以优化整流器的电阻和电容损耗。 使用模块温度和工作频率的数据，软件可以创建一个反馈回路，动态调整整流器设置，以达到最佳的效率。
