net/ PG-SCT-595 Functional Description The TLE 4240-2/3 M is a monolithic integrated low dropout linear constant current source.
It is designed to supply white or color LEDs in order to achive constant brightness and extended LED lifetime independent from supply voltage or LED forward voltage class.
Protection circuits prevent from damage to the device in case of overload, short circuit, reverse polarity and overheat.
The LEDs connected are protected against reverse polarity transients as well as against voltages up to 45 V.
The Safe Operation Area (SOA) monitoring function limits the output current in case of a very high drop voltage across the regulator.
For details see graph “Output Current versus Drop Voltage”.
Version TLE 4240-3 M is equipped with a status output indicating an open load failure condition.
The TLE 4240-2/3 M is supplied in a space-saving PG-SCT595-5 package offering minimal thermal resistance.
