MxC 292 +5V Buck Reg. Output EVB
The MxC 292-EB3-C +5V Buck Reg. Output EVB can be operated as a standalone regulated 5V
output board. The EVB utilizes the 2D_048_015B MxC 200 family device.
When the MxC 292 is providing power to another SMPS, the synchronization feature of the
2D_048_015B allows the MuxCapacitor switching to slow down as the SMPS enters pulse
skipping. This operation reduces switching power losses at no-load to light-load conditions. The
EXTCLK can be provided by either a FET gate drive signal or a buck regulator’s switched output
to enhance light-load efficiency. Both the EXTCLKSEL and EXTCLK inputs accept up to 30V
signals.
