POWER SUPPLY
The DLP-EVALx boards take all needed operational power from the host PC's USB port via the
DLP-USB245M USB Adapter. When the host PC goes to standby mode, the DLP-USB245M will also go
to standby mode after 3 milliseconds of no USB activity. When the DLP-USB245M goes to standby
mode, it takes SLEEP high, which powers down the DLP-EVALx board.
Both the EVALP and EVALS circuits employ a P-channel MOSFET to control power. Once Windows has
enumerated the DLP-USB245M module, the FT245BM takes its SLEEP line low. This circuit could also
be used to control power to higher-current applications since the RC network connected to the gate of the
MOSFET sets the rise-time (limiting the inrush current) for the power going to the target electronics.
