This page documents the power supply board for the FLARE CCD camera.  It must provide the following voltages

|| ''''Voltage''' || '''Use''' || '''Total Current''' || '''Destination''' || '''Notes''' ||
|| -5V || Horizontal Clocks || 810mA || CCD Boards || See CCD spec p25, not clear what V should be! ||
|| -9V || Vertical Clocks || 105mA || CCD Boards || -8.5...-9.5 per spec ||
|| +12V || Vertical Clocks || 36mA || CCD Boards || +11.5...+12.5 per spec ||
|| +3V || Reset Gate || 30mA || CCD Boards || +2.5...+4.0 per spec ||
|| -3V || Reset Gate || 30mA || CCD Boards || -1.5...-3.5 per spec but diff must be <= 5V ||
|| +15V || CCD output amps and R(d) (12V via r-divider) || 300mA || CCD Boards || +14.5...+15.5 per spec ||
|| +3.3V || AD9928 supply || 300mA || CCD Boards || Should be 3.0V ||
|| +30V || Substrate Bias || 12mA || CCD Boards || +29...+40 per spec, shutter V(H) ||
|| +5.5V || Regulator Bias || 50mA || FPGA Board || ||
|| +3.6V || All FPGA, MGT, SFP, DDR3 || 2.5A (WAG) || FPGA Board || ||
|| +3.6V || TECs and Motors || 7.5A (abs max) || TEC/Motor Board || ||

Current power-up and power-down sequencing must be observed.  The power input is 24V bulk from the cart.  A microcontroller provides control and monitoring, and is connected to the FPGA board by a 9600 baud asynchronous serial link.

=== ECOs (Errors) in V1.0 Layout ===

* Pins 11, 12 are swapped on J4, J5, J7 (power headers for CCD boards)
* Missing pull-up resistors (10k) on I2C bus (SDA, SCL)
* Change Pull-down to pull-up on EN_3.6V (R34).
* Add two additional pins to 3.6V output for TEC/SMC board.  _confirm final pinout_
* Add pull-down discharge resistor on -9V (VL). _check others_
* Fix resistor divider for +15V (now +15.85 nom, 16V observed)  Max for AD9928 is +17.5, so maybe ok?
* Change -3.0 to -2.0 ??
