Alternate Designs
Alternate designs with the LM3429 evaluation board are pos-
sible with very few changes to the existing hardware. The
evaluation board FETs and diodes are already rated higher
than necessary for design flexibility. The input UVLO, output
OVP, input and output capacitance can remain the same for

the designs shown below. These alternate designs can be
evaluated by changing only R9, R10, and L1.
The table below gives the main specifications for four different
designs and the corresponding values for R9, R10, and L1.
PWM dimming can be evaluated with any of these designs.
