48V输入,36.5V/8A输出,TI工程师们有没有办法消除波浪曲线?
Hi
Datasheet仅仅说明了: For most of the applications, CCOMP of 100 nF to 470 nF is good enough. Additionally, TI recommends a high quality ceramic capacitor with X7R dielectric rated for 25 V.
电路上L1建议去掉,VIN电容尽量靠近VIN脚。
MOS管发烫,将驱动电阻以及二极管渠道看看。

HI
LED电流越大(10A上升到12A), 电流上冲越大,是否有更换更大饱和电流的电感看看?
应该是电流异常后,导致sense电阻异常的增加功耗。
