Infineon TLE4241 GM LED Driver Datasheet
The TLE4241 GM is an integrated adjustable constant‑current LED driver supplied in a very small P‑DSO‑8‑9 (Micro‑8) package. It offers a wide input voltage range, adjustable output current via SET pin, PWM input, or a reference resistor, and includes overtemperature, short‑circuit, reverse‑polarity, and open‑load protection.
The document provides pin definitions, a typical application circuit, absolute maximum ratings, operating ranges, and detailed electrical characteristics such as output current levels, drop voltage, and PWM input thresholds.

Questions answered in these manuals
What is the input voltage range of the TLE4241 GM?
The device operates from 4 V up to 45 V.
How can the output current be set?
Output current can be adjusted via the SET pin, a reference resistor on the REF pin, or by changing the PWM duty cycle.
What is the function of the PWM input?
The PWM input adjusts LED brightness by varying duty cycle and can also be used as an enable input; setting PWM low puts the device into a low‑current sleep mode.
In which package is the TLE4241 GM supplied?
It is provided in a very small P‑DSO‑8‑9 (Micro‑8) surface‑mount package.
