I used slur815.pdf for my design.
Attached my circuit.
When testing at a load of 0-10A. no problems. Everything was fine until recently. There were problems at the start of one of the devices in which my power source was used. It turned out the problem appeared due to the fact that the 12V bus was increased capacity to 4000uF. Total, taking into account the output capacitance of the power source itself was about 5000uF.
I repeated the manifestation of this problem on the resistive load 1A, in combination with a 4000uF capacitive load.
I started experimenting. The first thing I tried, increased Rss to 0.47uF. But this did not have a noticeable improvement.
C41 (in my design) had a noticeable effect. I increased this capacity to 10uF. The device began to start. But still, if you make a series of on and off, then you can achieve a cyclic restart of my switching power supply.
Please help in further customization. I'm worried about the acceptability of the “C41” change to solve my problem. In designs that I've seen, everywhere this capacity was 4.7uF.
