Design TL4242-Q1
SLVS732G – JULY 2010 – REVISED APRIL 2017 TL4242-Q1 Adjustable LED Driver
1 Features 3 Description The TL4242-Q1 device is an integrated adjustable
constant-current source, driving loads up to 500 mA.
One can adjust the output current level through an
external resistor. The device design is for supplying
high-power LEDs (for example, OSRAM Dragon LA
W57B) under the severe conditions of automotive
applications, resulting in constant brightness and
extended LED lifetime. The device comes in the DRJ
(WSON) and KTT (TO-263) package. Protection
circuits prevent damage to the device in case of
overload, short-circuit, reverse polarity, and overheat.
The device provides the connected LEDs protection
against reverse polarity as well as excess voltages up
to 45 V. 1 Qualified for Automotive Applications
