Unfortunately, our previous regulator (AP65200) is out of stock and looking like it's EOL. We plan on switching to a power module/DC-DC to hopefully save space and allow for a 2-layer board.
Our goal is to find a max 16V to 3.3V converter at around 500mA peak. We're assuming that nothing too powerful will be running off of the 3.3V rail, so 500mA gives us a bit of overhead for the CAN transceiver, MCU, and LEDs present on the controller board.
Options
The options below are reasonably priced and have relatively low output ripple at light loads.
- Recom Power ROF-78E3.3-0.5SMD-R
- Texas Instruments TPS82130SILT
- Volgen America/Kaga Electronics USA PM-500A33
