摘要： A mixed signal integrated circuit device, e.g., digital-to-analog converter (DAC), has a serial interface communication protocol that accesses volatile and/or non-volatile memory and allows a preprogrammed output voltage whenever the mixed signal device is powered- up. However, unlike conventional DACs, DACs with non- volatile memory may need special interface communication protocols for effective operation of the DAC and communications between a system master controller unit (MCU). Interface communications protocols that do not violate standard serial bus communications protocols are provided for communicating between the volatile and non- volatile memories of the DAC so that the MCU may access the DACs memories (non-volatile and/or volatile memories). The mixed signal integrated circuit device has a user programmable address.

摘要： 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.
摘要翻译：高压开关稳压器在测量输入电流和产生感测电流值之间显着降低了电流感测延迟，同时通过使用电流复制和电流传送器保持通过功率晶体管的电流的高精度。输入电流的高检测精度确保良好的负载调整率，低感应延迟确保在宽范围的输出电流和高输入输出电压比下的固定占空比。电流传送器用于将高侧电流值传送到低侧控制电路，例如脉宽调制（PWM）控制。电流传送器始终打开，例如，总是存在一些电流，从而使任何电流测量延迟最小化。这是通过将电流传送器通过消耗等于感测电流的电流而动态偏置来实现的。其中确保电流传送器的平衡并且使电流传送器的输入处的偏移最小化。
