TPS51120 max duty cycle

Other Parts Discussed in Thread: TPS51120

您好 我想请教下TPS51120的几个问题:

1,在重载下(5A)的最大duty cycle能开到多少?

2,Dynamic UVP  功能是否可以disable?

3,  TPS51120 是否有pin to pin的可替代料?

4,  像TPS51120这样的dual output 的,duty cycyle可以开到99%的有哪几个?交期比较好的要多久?

谢谢。

  • 你好,一般来说,D-CAP的磁滞环路在负载调节时的duty cycle可以开到100%,这片子我没测过,不知道要不要留一点时间给boot strap。

    UVP功能是可以禁止掉的,具体参考数据手册12页。
