The regulation and tolerances do not account for thermal drifting and
component tolerance of the output diode forward voltage drop and voltage
drops across the LC post filter. The actual voltage values are estimated at full
load only.
Please verify cross regulation performance on the bench.
Errors, Warnings, Information
Description
To increase lifetime of
LED driver applications
select capacitor with high
ripple current rating.
Such capacitors
experience smaller
temperature rise.

Ref.
#
For every 10 degrees drop in operating
temperature the capacitor lifetime
approximately doubles.
