The high-speed modes (DRATE = 100, 101) are supported in high-speed LVDS interface mode only. The state of the LVDS pin and the SCLK_SEL are ignored. In these two modes, an on-chip PLL is used to multiply the input clock (CLK) by three, to be used for…
Other Parts Discussed in Thread: LM43601 我参考了ti的反向step down 电路 设计, 使用LM43601 芯片 设计+12V to -12V的电路。
做了块小的evaluation board 负载是电阻负载,一切功能正常。
但新设计的板子上使用了同样的电路，板上有3.3V的电源,±12V用于给AD和运放供电,当3.3V电源先上电时,dc-dc电路输出始终是0.5V,
如果先输入12V电源,-12V的输出正常,目前不知道是什么问题。
