The TPS75103YFFR, which is classified into PMIC – LED drivers, is a dual-channel step down DC-DC synchronous converter. It is an ideal solution to those power applications requiring two regulated outputs, either both positive or one positive and one negative, while the input voltage source is ranging from 1.8V to 5.5V. The offered output voltage of the TPS75103YFFR can be adjustable within the range of 0.7V~3.3V, and the output current can reach up to 1.25A per channel.

The physical characteristic of TPS75103YFFR is that it has a 2×2 DFN package with a 0.4mm pitch, which is much smaller than other kinds of converters, offering a more strategic placement of components and a smaller printed circuit board layout. As for the working principle, the TPS75103YFFR utilizes a current mode architecture synchronous buck converter, which is suitable for high efficiency, fast load transient response, and stable operation at a lower value inductor and output capacitance. It also features fixed frequency operation and internal compensation to allow for accurate, low noise regulation of both outputs.

The TPS75103YFFR is designed to be suitable for used in battery operated applications. More specific application fields include but are not limited to the power management of various electronic products such as toys, automotive electronics, and so on. Due to its small size, low power dissipation and low cost, it can be the best choice to be used in mobile application, like cellphones and tablet PCs, whose energy consumption or size has to be minimized.

In conclusion, the TPS75103YFFR is an ideal choice as a dual-channel step down DC/DC converter, and its small size makes it especially suitable for portable electronic device applications. It is also capable of current mode architecture synchronization with low noise regulation of both its outputs. Moreover, its outputs are adjustable within the range of 0.7V~3.3V at a current of up to 1.25 A per channel. Therefore, the TPS75103YFFR is a great cost-effective choice within PMIC-LED drivers.
