TLE4309G Description

Short technical summary and product information.

The TLE4309G from Infineon Technologies is an integrated adjustable constant current source designed for driving loads up to 500 mA. This linear LED driver ensures constant brightness independent of supply voltage or LED forward voltage variations, extending LED lifetime by protecting against overcurrent and overtemperature.

 

The device operates with a supply voltage range of 4.5 V to 24 V, with a maximum supply voltage of up to 45 V. It features a low dropout voltage and a PWM/ENABLE input for brightness regulation. When disabled, the quiescent current is less than 1 µA. Protection features include overtemperature protection, short circuit proofing, and reverse polarity protection.

 

The output current level can be adjusted using an external shunt resistor. The TLE4309G is supplied in a surface-mounted PG-TO-263 package, offering excellent thermal resistance. It is suitable for applications with ambient temperatures up to 85 °C.

 

Key features include adjustable constant current up to 500 mA, a wide operating supply voltage range, low dropout voltage, PWM/ENABLE input, and integrated protection circuits. The device is also RoHS compliant.
