8. MxC 284 Voltage Boost with LED Current Source Output EVB

The MxC 284-EB2-C Voltage Boost with LED Current Source Output EVB adds a current source
regulator to the output of the MxC 200. The EVB utilizes the 2U_012_010A MxC 200 family
device.
The low 9V battery voltage is boosted to 36V to accommodate a high output, high efficiency
LED. The MxC 284 is populated with a single high output white LED. Alternatively, the "spot"
LED can be replaced with a LED back panel, see Figure 23.
Higher LED currents can be supplied with a corresponding current source driver and additional
MxC 284 fly and hold capacitance.
The input voltage range is 6V to 12V for an output voltage range of 24V to 48V, respectively.
