Product Description

Low Price Quality LM3553SDXNOPB Texas Instrument Electronic Components In Stock. LM3553SDXNOPB 1.2A dual flash LED driver System with I2C compatible interface belongs to of Texas Instruments(TI).The LM3553 is designed to use a 2.2µH inductor. When the device is boosting (VOUT > VIN) the inductor is one of the biggest sources of efficiency loss in the circuit. 


Therefore, choosing an inductor with the lowest possible series resistance is important. Additionally, the saturation rating of the inductor should be greater than the maximum operating peak current of the LM3553. This prevents excess efficiency loss that can occur with inductors that operate in saturation and prevents over heating of the inductor and possible damage.


The LM3553 is a fixed frequency, current mode step-up DC/DC converter with two regulated current sinks.The device is capable of driving loads up to 1.2A from a single-cell Li-Ion battery. 


The LM3553 includes a TX pin that forces Torchmode during a flash event allowing for synchronization between the RF power amplifier andFlash/Torch modes. It also includes a multi-function pin (M/F) that can serve as a GPIO and a hardware RESET pin. The LM3553 is available in a 3mm by 3mm package.
