Linear Technology LTC3417EDHC#PBF Dual Synchronous Step-Down DC/DC Regulator

The LTC3417EDHC#PBF is a highly efficient, dual-channel, synchronous step-down DC/DC regulator from Linear Technology, designed to provide high-efficiency power management for a wide range of applications. This compact and robust component is ideal for portable devices, where maintaining extended battery life is critical. Its dual-channel design allows for the simultaneous regulation of two independent output voltages, which can be adjusted via external resistors.

With an input voltage range of 2.25V to 5.5V, the LTC3417EDHC#PBF is versatile enough to accommodate various power sources, including single-cell lithium-ion batteries. Each channel is capable of delivering up to 800mA of continuous output current, ensuring reliable performance for demanding applications. The high switching frequency of up to 4MHz allows the use of small, low-cost capacitors and inductors, minimizing the overall solution footprint on the PCB.

The LTC3417EDHC#PBF incorporates internal switches with RDS(ON) of only 0.25 ohms, which helps to reduce power loss and improve efficiency. Its synchronous rectification design contributes to maximizing efficiency, which can reach up to 95%, thereby reducing heat generation and improving system reliability. The device also features Burst Mode® operation, which further enhances efficiency at light loads by reducing quiescent current.

For protection and reliability, the LTC3417EDHC#PBF is equipped with a range of features including over-temperature protection, current limiting, and short-circuit protection. The device also offers selectable Burst Mode operation, which can be enabled or disabled according to the requirements of the application. This allows designers to make trade-offs between efficiency and output ripple based on specific needs.

Available in a 16-lead DHC package, the LTC3417EDHC#PBF is designed for space-constrained applications. Its compact form factor, combined with its power density and efficiency, makes it an excellent choice for portable electronics, such as handheld medical devices, GPS units, and wireless routers, where dual power rails are required.

With its advanced features and high-performance capabilities, the LTC3417EDHC#PBF from Linear Technology is a reliable and versatile solution for modern electronic designs requiring efficient dual-channel power regulation.
