About this document
Scope and purpose
The purpose of the TLD2252-2EP rear combination lamp evaluation board (TLD2252-2_RCL_EVAL) board is to
help designers evaluate the features and the performance of the TLD2252-2EP, a two-channel linear current
source LED driver for automotive LED lighting applications. TLD2252-2EP provides a simple and compact
solution for the implementation of a rear combination lamp (RCL).
This user manual provides the usage instructions of the TLD2252-2 _RCL_ EVAL board (schematic version S00,
PCB version P00).
