Voltage
regulator
This module must have 5V supplied through the TIM connectors. In addition, a 3.3V
supply is required and should be supplied through the TIM mounting holes. This is
compatible with the SMT310Q, SMT327 and future Sundance TIM carrier boards.
Contained on the module are a linear regulator for the ‘QDRs and a DC/DC converter
for the FPGA.
DC/DC Converter
This module is designed to provide up to 20A of low voltage supply to the FPGA from
a single 5V input. The output voltage provided is a Vout of 1.5V.
Current limiting is provided if more than 20 A are drawn out of the DC\DC converter.
