Linear Technology's LTC3417AEDHC Dual Synchronous Step-Down DC/DC Converter

The LTC3417AEDHC is a high-performance, dual-channel synchronous step-down DC/DC converter produced by Linear Technology, a leader in analog integrated circuits. This compact and efficient power management solution is designed for portable and space-constrained applications where dual power rails are required.

Each channel of the LTC3417AEDHC is capable of delivering up to 800mA of continuous output current, making it suitable for powering a variety of digital and analog circuits. The device operates from an input voltage range of 2.5V to 5.5V, which allows for flexibility in battery-powered scenarios, including single-cell Li-Ion or multi-cell alkaline/NiMH applications.

The LTC3417AEDHC features a high switching frequency of up to 4MHz, which enables the use of small, low-cost capacitors and inductors, thus reducing the overall footprint of the power supply design. This high frequency also allows for fast transient response, a critical feature for maintaining voltage stability in dynamic load conditions.

With its internal synchronous switches, the LTC3417AEDHC provides high efficiency, which is crucial for maximizing battery life. The device also offers selectable Burst Mode® operation, which reduces quiescent current to only 25µA per channel during light load conditions, further extending battery runtime.

The LTC3417AEDHC incorporates a range of protective features to ensure reliable operation under adverse conditions. These include over-temperature protection, over-current protection, and a power good status output for each channel. The device is available in a 16-lead DFN package with a compact 3mm x 3mm footprint.

In summary, the LTC3417AEDHC from Linear Technology is an ideal choice for designers looking for a dual output, high-efficiency, synchronous step-down converter that saves space and extends battery life in portable applications.
