Macrofab Engineering Podcast

Hosts: Parker Dillmann Stephen Kraig Guests: N/A Figure 1: SSPS front panel layout. Traces to come soon. Figure 2: Inconsistencies in the LTST-C171CKT datasheets. Podcast Notes Stephen is still working on customer fixtures but managed to get some progress on the FX Development Board. Stephen has been working on the documentation to get the Crowd Supply fundraising going. Still need to prototype the enclosure. Parker has been working on the SSPS front panel design. See Figure 1. Parker is going to use Omron's B3W-9000-RG2C illuminated switches because it has a Red and Green LED and allows for custom key caps via printable transparencies. The Bourns' PEL12T-4226F-S1024 RGB Encoder will function to adjust the power on the supply. This is a 2-bit encoder with a clear shaft that is illuminated with a RGB LED. Instead of 74HC595s, Parker is going to use a STP16CP05 LED driver. The IC is a 16-bit constant current sink driver. He chose the TSSOP-24 package because it has a thermal pad to heat dissipation.
