Linear Technology LTC3417AIFE Dual Synchronous Step-Down DC/DC Regulator

The LTC3417AIFE from Linear Technology is a high-performance, dual-channel, synchronous step-down DC/DC regulator designed to provide efficient power management for a variety of applications. This compact and versatile regulator is capable of delivering up to 800mA of continuous output current from each channel at output voltages as low as 0.8V, making it an ideal choice for portable and space-constrained devices.

One of the key features of the LTC3417AIFE is its wide input voltage range, which spans from 2.5V to 5.5V. This allows the device to operate from a variety of power sources, including single-cell lithium-ion batteries, multi-cell alkaline batteries, or regulated 5V power supplies. The wide input range, combined with its low dropout operation, ensures consistent performance even when the input supply voltage is close to the output voltage.

The LTC3417AIFE integrates two internal switches with low RDS(ON) to minimize losses and enhance efficiency. With its synchronous rectification design, the regulator achieves high efficiency across a wide range of load currents, which is critical for extending battery life in portable applications. Efficiency is further maximized with a selectable Burst Mode® operation, which reduces quiescent current during light-load conditions.

Designed with flexibility in mind, the LTC3417AIFE offers programmable switching frequencies from 1MHz to 4MHz, allowing designers to optimize the regulator for efficiency or component size. The higher switching frequency enables the use of smaller, low-cost capacitors and inductors, which is beneficial for space-constrained applications.

Additional features of the LTC3417AIFE include independent shutdown and soft-start functions for each channel, over-temperature protection, and over-current protection. These built-in safety features protect the device and the end application from adverse conditions.

The LTC3417AIFE is available in a compact, thermally efficient 24-lead TSSOP package with an exposed pad for improved thermal performance. Its robust design and comprehensive feature set make it an excellent choice for powering the latest portable and high-density systems.

Overall, the LTC3417AIFE is a reliable and efficient solution for dual-channel power supply requirements, offering the performance and flexibility needed to meet the demands of modern electronic devices.
