The TLD5045EJ from Infineon Technologies is a highly integrated smart LED buck controller. It is designed to efficiently drive single or multiple series-connected LEDs by regulating a constant LED current (ILED), which is crucial for LED color accuracy and longevity.
This device features a wide input voltage range from 5 V to 40 V and allows for output currents up to 700 mA, adjustable via external low-power resistors. The switching frequency is typically 200 kHz and can be adjusted using an external RC network. It includes an integrated PWM dimming engine for decentralized light modules without microcontroller involvement.
The TLD5045EJ is housed in a PG-DSO-8 EP package and is suitable for surface mounting. It incorporates built-in protection functions, including overtemperature protection, undervoltage, and overvoltage shutdown with hysteresis. Its low current consumption in sleep mode (< 2 µA) makes it energy-efficient.
Potential applications include automotive LED exterior lighting such as brake lights, tail lights, and daytime running lights, as well as interior lighting like reading lights and dome lights.
