Driving White LED’s
Driving white light emitting diodes in series. An alternative
to the MCP1252 backlighting approach is to drive the
white light emitting diodes in series. The series connection
provides improved brightness matching between the diodes
since they all operate with the same current. Light intensity
is adjusted by controlling the current through the diodes. The
MCP1650 is a boost controller that can be used to bias the
diodes in series as depicted below.
