MxC 290 Triple 24V/12V/6V Output EVB
The MxC 290-EB9-C Triple 24V/12V/6V Output EVB can be operated as a standalone fixed
frequency voltage reducer or synchronized with a SMPS. The EVB utilizes the 2D_048_015A
MxC 200 family device.
When the MxC 290 is providing power to a SMPS, the synchronization feature of the
2D_048_015A 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.
Both the EXTCLKSEL and EXTCLK inputs accept up to 30V signals.
