This application note presents a reference design for a rear combination lamp (RCL) LED driver in a 3-series, 3-parallel (3S3P) configuration. Using the MAX16823 linear driver and external BJTs, this design provides 200mA per string as well as enhanced heat dissipation. Also included is PWM dimming circuitry for tail-light inputs and full brightness for brake-light inputs. Double-battery and load-dump conditions have been taken into consideration.
