Quality Control: Learn More
The Texas Instruments LM3503SQX-35-NOPB is a high-performance LED driver IC designed for demanding backlight applications. This DC-DC regulator features a step-up (boost) topology with two outputs, capable of delivering up to 35V. Each output channel supports a maximum switch current of 750mA, facilitating efficient driving of LED arrays.
The device integrates internal switches and offers both analog and PWM dimming capabilities, allowing for precise control of LED brightness. Operating at a frequency of 1MHz, the LM3503SQX-35-NOPB is suitable for a wide range of operating temperatures from -40°C to 85°C. It is supplied in a compact 16-WQFN (4x4) package, suitable for surface mounting. The input voltage range is 2.5V to 5.5V.
