Description

LTC3407EDD Dual-Channel, 1.5MHz Synchronous Step-Down Regulator

The LTC3407EDD from Linear Technology is a high-performance, dual-channel synchronous step-down regulator that operates at a switching frequency of 1.5MHz. This compact and efficient device is designed to minimize the size of external components while providing flexible and robust power management solutions for a variety of applications.

Encased in a small 3mm x 3mm DFN package, the LTC3407EDD integrates two independent channels that can deliver up to 600mA of continuous output current per channel. The high switching frequency allows the use of tiny, low-cost capacitors and inductors, reducing the overall footprint and cost of the power supply circuit.

Each channel of the LTC3407EDD is capable of operating from an input voltage range of 2.5V to 5.5V, making it suitable for single-cell Li-Ion, multi-cell alkaline, or NiMH applications, as well as standard 3.3V and 5V power rails. The output voltage is adjustable from 0.8V to VIN, allowing for a wide range of output voltages to accommodate various digital and analog loads.

The LTC3407EDD features internal synchronous rectification, which enhances efficiency by eliminating the need for an external Schottky diode. This, combined with its 100% duty cycle capability, ensures low dropout performance, critical for battery-operated devices that require maximum runtime. The regulator maintains high efficiency throughout the entire load range, which is essential for portable and battery-powered applications where power conservation is paramount.

Additional features of the LTC3407EDD include independent soft-start functions for each channel to limit inrush current during startup, short-circuit protection, and thermal overload protection to safeguard the device and the load under adverse conditions. The chip also offers selectable Burst Mode operation, which reduces quiescent current and improves efficiency at light loads.

Overall, the LTC3407EDD is an excellent choice for designers looking for a dual-channel, high-efficiency, and space-saving step-down regulator. Its ability to deliver high performance in a small package makes it ideal for portable devices, wireless products, and other space-constrained applications that require reliable and efficient power management.
