Description: The AMC2576 series is a step-down switching regulator with all the required active functions. It is capable of driving 3A load with excellent line and load regulations. These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version.
The AMC2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It requires only a minimum number of external components. Substantially, it reduces not only the area of board size but also the size of the heat sink. In some cases, no heat sink is required.
The ± 4％ tolerance on output voltage within specified input voltages and output load conditions is guaranteed. The oscillator frequency accuracy is within ±10％. External shutdown is included, featuring 70 A(typical) standby current. The output switch includes cycle-by-cycle current limitation, as well as thermal shutdown for full protection under fault conditions.

Description: 做DSP最应该懂得157个问题（回答）
四.5V/3.3V如何混接？
TI DSP的发展同集成电路的发展一样，新的DSP都是3.3V的，但目前还有许多外围电路是5V的，因此在DSP系统中，经常有5V和3.3V的DSP混接问题。在这些系统中，应注意： 1)DSP输出给5V的电路（如D/A），无需加任何缓冲电路，可以直接连接。 2)DSP输入5V的信号（如A/D），由于输入信号的电压>4V，超过了DSP的电源电压，DSP的外部信号没有保护电路，需要加缓冲，如74LVC245等，将5V信号变换成3.3V的信号。 3)仿真器的JTAG口的信号也必须为3.3V，否则有可能损坏DSP。
五.为什么要片内RAM大的DSP效率高？

Lower cost to achieve higher integration, but also promoted the geometry of a smaller demand. As the size decreases, the transistor breakdown voltage becomes lower, and ultimately, when the breakdown voltage below the supply voltage, then reduce the supply voltage requirements. Thus, with the speed and complexity of the increase, for high-density devices, the inevitable consequence is that the power supply voltage from 5V to 3.3V, or 1.8V.

Microchip 单片机的速度和复杂性已经到达足以要求降低电源电压的程度，并正在向5V 电源电压以下转换。但问题是绝大多数接口电路仍然是为5V电源而设计的。这就意味，作为设计人员，我们现在面临着连接3.3V和5V 系统的任务。此外，这个任务不仅包括逻辑电平转换，同时还包括为3.3V系统供电、转换模拟信号使之跨越3.3V/5V的障碍。-3V 5V system connection skill
