The LTC3417AEDHC-2 is a high-performance, dual-channel, synchronous step-down DC/DC regulator manufactured by Linear Technology, a leader in high-performance analog integrated circuits. Each channel of the LTC3417AEDHC-2 is capable of delivering up to 1.25A of continuous output current at voltages as low as 0.6V, making it an ideal choice for portable applications requiring high efficiency and battery life.

Operating over a wide input voltage range from 2.5V to 5.5V, the LTC3417AEDHC-2 is perfectly suited for single-cell Li-Ion, multi-cell alkaline or NiMH, as well as other standard power sources. The device's high 4MHz switching frequency enables the use of small, low-cost capacitors and inductors, reducing the overall footprint and cost on the PCB.

The LTC3417AEDHC-2 features internal switches with RDS(ON) of only 0.35Ω and 0.45Ω for the high-side and low-side switches, respectively, which minimizes power loss and improves efficiency. With efficiency as high as 95%, this regulator ensures extended battery life in portable applications.

Each channel of the LTC3417AEDHC-2 operates 180 degrees out-of-phase, which helps to reduce the input ripple current, resulting in a smaller and more cost-effective input capacitor. The device also offers selectable Burst Mode® operation, which further enhances efficiency at light loads by reducing quiescent current.

Additional features include a Power Good voltage monitor, over-temperature protection, and current mode operation for excellent line and load transient response. The LTC3417AEDHC-2 comes in a compact, thermally efficient 16-lead DHC package, making it a practical choice for space-constrained applications.

Whether you are designing power supplies for handheld devices, portable media players, or other battery-powered electronics, the LTC3417AEDHC-2 provides a reliable, efficient, and space-saving solution that meets the rigorous demands of modern portable electronics.
