|
### Thermal management
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
* Most of the heat from the IC seems to be dissipating though the OUT1 / OUT2 pins
|
|
|
|
|
|
|
|
* Therefore, the OUT1 / OUT2 polygons should be enlarged, for better cooling
|
|
|
|
|
|
|
|
* Maybe the IC should be moved more towards the middle of the board
|
|
|
|
|
|
|
|
* Right now the board can barely handle 5A
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### Solderability
|
|
|
|
|
|
|
|
* The large cap is very difficult to solder
|
|
|
|
|
|
|
|
* Some thermal reliefs can make it much easier, while probably not impacting performance in any significant way
|
|
|
|
|
|
|
|
* The optional flyback diodes are difficult to solder
|
|
|
|
|
|
|
|
* The footprint should be made hand-solderable (by enlarging the pad by a lot)
|
