LTC3407AEDD-2#TRPBF - High Efficiency, Dual Output Synchronous Step-Down Regulator

The LTC3407AEDD-2#TRPBF is a high-performance, dual-channel synchronous step-down voltage regulator from Linear Technology, designed to deliver efficient power management for portable and compact electronic devices. This regulator features two independent output channels that can deliver up to 600mA of continuous output current per channel at voltages as low as 0.6V, making it an ideal choice for powering the latest generation of low-voltage digital ICs.

With an input voltage range of 2.5V to 5.5V, the LTC3407AEDD-2#TRPBF is perfectly suited for single-cell Li-Ion/Polymer or multi-cell alkaline/NiMH applications. It offers a high switching frequency of up to 2.25MHz, which allows the use of tiny, low-cost capacitors and inductors, reducing the overall solution footprint and making it an excellent choice for space-constrained applications.

The LTC3407AEDD-2#TRPBF incorporates internal switches with RDS(ON) of only 0.35Ω and 0.45Ω for the high side and low side respectively, ensuring high efficiency across a wide range of load currents. It also features Burst Mode® operation, which significantly improves efficiency at light loads and extends battery life. For noise-sensitive applications, the regulator can be synchronized to an external clock or switched to a fixed frequency mode to minimize interference.

Additional features include a Power Good status output, over-temperature protection, and current mode operation for excellent line and load transient response. The LTC3407AEDD-2#TRPBF is available in a compact 10-lead (3mm x 3mm) DFN package, providing a thermally efficient solution with a low profile that is ideal for modern electronics where space is at a premium.

Linear Technology's LTC3407AEDD-2#TRPBF regulator is a robust and versatile solution for designers looking to enhance power efficiency and prolong battery life in their portable and space-sensitive applications. With its advanced features and compact design, it offers an optimal balance of performance and size for a wide array of portable devices.
