Other Parts Discussed in Thread: UCC27517
Dear all:
I have some functional issues about UCC27511。
1. The drive current specification is: 4-A Peak Source and 8-A Peak Sink. The current difference between the two is so large. How is this achieved?
2. For Noninverting Input circuit, Can the power inductor be removed? if we want to output 3.5A or 4A drive current, how to choose VDD and VSOURCE voltage? What are the specifications of high-speed MOS tubes that require special attention (switching speed, node capacitance, Rdson), how to confirm the specifications?
3. How does the actual drive current calculate the required current value based on the peripheral device and operating voltage?
