L6205N PowerDIP not PowerSO #101

Open rusefillc opened 2 years ago

rusefillc commented 2 years ago

We have exhausted L6205PD stock at JLCPCB While I am trying to snatch remaining tube packaged L6205PD we have to consider the L6205N PowerDIP option for two reasons

1) JLCPCB might be able to acquire L6205N for us C962260 2) if not, PowerDIP would be 400 times simpler to solder on US soil

See https://datasheet.lcsc.com/lcsc/1810241722_STMicroelectronics-L6205PD013TR_C36543.pdf

When you have shit to deal with, remember that it is s fertilizer and plant crops.

@andreika-git suggests real-life testing on a prototype board

wow mouser has a few of EVAL6205N

Thermal performance is going to be shit compared to powerso. They do make heatsinks that can be used, both clip on and glue on. Id probably recommend a thermal adhesive for this because vibration. The #1 case where problems will occur is not a current RE test vehicle: centrifugal blower (vortec and procharger) at medium (25-50%) throttle with a large throttle plate. In this murder case, you have the worst case high velocity airflow and the case where you’re trying to maintain a steady throttle with strong forces (from air velocity). You’re going to be at significant duty for sustained periods of time. Duty x time = thermal load.

I’m 100% convinced you will be able to make this chip run an ETB. You’re going to run into trouble on the endurance race. You’re going to run into trouble with demanding ETB applications like my 102mm TB + D1sc SC nightmare example. Does this matter for what you’re going to use it for? Maybe. If you want help torturing your evaluation boards appropriately, lmk.
