    • A high voltage switching regulator has significantly reduced current sensing delay between measurement of input current and generation of sensed current values, while maintaining good accuracy of the current through a power transistor using current replication and a current conveyor. High sensing accuracy of the input current ensures good load regulation, and low sensing delay ensures fixed duty cycle over a wide range of output currents and high input to output voltage ratios. A current conveyor is used to transfer high side current values to low side control circuits, e.g., pulse width modulation (PWM) control. The current conveyor is always on, e.g., some current flow is always present, thus minimizing any current measurement delay. This is accomplished by dynamically biasing the current conveyor by draining to ground a current equal to the sensed current. Wherein balancing of the current conveyor is ensured and offset at the input of the current conveyor is minimized.
    • 高电压开关调节器在测量输入电流和产生感应电流值之间大大减少了电流检测延迟,同时通过使用电流复制和电流输送机的功率晶体管保持了良好的电流精度。 输入电流的高感测精度确保良好的负载调节,并且低感测延迟确保在宽范围的输出电流和高输入到输出电压比下的固定占空比。 目前的输送机用于将高侧电流值传送到低端控制电路,例如脉冲宽度调制(PWM)控制。 当前的输送机总是打开,例如,一直存在一些电流,从而最小化任何电流测量延迟。 这是通过将等于感测电流的电流通过引流接地来动态地偏置当前输送机来实现的。 其中确保了当前输送机的平衡,并且在当前输送机的输入处的偏移被最小化。
