HW v1 Errata
- INA226: Hierarchical labels for A0/A1 are swapped
- Fix in v1: none (no address collision, no problem)
- DAC80501: Symbol error (SPI2C Pin is 4, not 3)
- Fix in v1: bodge wire (from Pin 4 to VDD)
- Power Supply:
- ADM7170: Fixed voltage versions need SENSE=VOUT
- Fix in v1: Populate R1 = 0 Ohm (instead of DNP as in schematic)
- LTC3624: Wrong feedback divider values (output voltages slightly too high)
- Fix in v1: Values corrected, see schematic
- LL-FET is too conductive (VEN does not rise above threshold)
- Use BC817 as replcaement (is pin compatible)
- LTC3624 produces in-band spurs in burst mode
- Use pulse-skipping mode instead (MODE=GND)
- LT3033 (at PA) current limit is too low
- Rail consumes 2A when operating, change 270R to 220R
- LT3033 does not turn on with 3.3V on EN
- Should work based on datasheet - perhaps defective IC?
- 744773068 RDC is on the high side
- at 130 mOhm produces 260 mV drop at 2 A current
