I'm working on LM2596 based voltage regulator circuit that will be printed on PCB.
According to LM2596 datasheet some traces should be kept as short as possible. However no numbers are given.
This is my design (with ground plane hidden), from left to right:
- LM2596S voltage regulator
- SS54 Diode
- 12.5mm 100uH Inductor
- 2x Low impedance 300uF capacitor
I'm a little bit worried about C In (capacitor on the right between input voltage and ground) connection with regulator. The trace length is about 35mm.
