| May 6, 2019 at 16:25 | comment | added | Bimpelrekkie | @Daniel That PDM1-S12-D12-S is not an IC but a module, just follow the guidelines on the datasheet, adding some decoupling capacitors is always a good idea (like 10 uF + 100 nF in parallel). The idea behind such modules is that they're "foolproof" and easy to use. | |
| May 6, 2019 at 15:06 | comment | added | Daniel | @Hearth, it was a very good tip. I found this model : PDM1-S12-D12-S ( digikey.com/product-detail/en/cui-inc/PDM1-S12-D12-S/… ) And, taking a look at it's datasheet I saw a EMC recommended circuit. It seems to be very simple, would you have some advice about layout and project using this kind of IC ? | |
| May 6, 2019 at 14:21 | comment | added | Hearth | The trick is to look for things with a minimum of 10.8V and a maximum of 13.2V input; 12V±10%. Digikey doesn't let you search by nominal input, just by input range, which is usually more useful but in cases like this can be unfortunately misleading. | |
| May 6, 2019 at 14:08 | comment | added | Bimpelrekkie | @Hearth I was looking for something like that but could not find them. Thanks. | |
| May 6, 2019 at 14:07 | comment | added | Hearth | Or just use one of these which all have a 12V input and a 12V output, and are isolated. Some of them even take an unregulated 12V input and output regulated ±12V! | |
