Linear Technology LTC3417AEFE Dual Synchronous Step-Down DC/DC Converter

The LTC3417AEFE is a high-performance, dual synchronous step-down DC/DC converter integrated into a single package, designed and manufactured by Linear Technology. This product is tailored to meet the demanding requirements of portable and compact electronic devices that require efficient power management solutions.

Featuring a wide input voltage range of 2.25V to 5.5V, the LTC3417AEFE is suitable for applications powered by single-cell lithium-ion batteries, multi-cell alkaline batteries, or other standard power sources. Each of its two channels is capable of delivering up to 800mA of continuous output current, making it a robust choice for powering dual supply systems.

The LTC3417AEFE utilizes a constant frequency, current mode architecture that provides excellent transient response and enables the use of small, low-cost capacitors and inductors. The high switching frequency of up to 4MHz allows for the use of tiny surface-mount components, resulting in a compact power solution that saves board space and reduces overall solution size.

With its internal synchronous switches, the LTC3417AEFE enhances efficiency by eliminating the need for external Schottky diodes, further simplifying design and reducing external component count. The device also offers selectable Burst Mode operation, which significantly improves efficiency at light loads and reduces standby power consumption, making it ideal for battery-powered applications where extending battery life is crucial.

Additional features of the LTC3417AEFE include independent shutdown and soft-start functions for each channel, over-temperature protection, and over-current protection, ensuring reliable operation under various conditions. The device is available in a thermally efficient, 20-lead TSSOP package with an exposed pad for enhanced thermal performance.

In summary, the LTC3417AEFE from Linear Technology is a versatile and efficient solution for dual channel power supply applications, combining high efficiency, compact size, and robust protection features. It is an excellent choice for designers looking to optimize power management in space-constrained and power-sensitive electronic devices.
