Linear Technology LTC3407EMSE#TRPBF Dual DC/DC Converter

The LTC3407EMSE#TRPBF is a high-performance, dual-channel synchronous buck regulator integrated circuit from Linear Technology, now part of Analog Devices. This compact and efficient power management solution is designed to convert input voltages ranging from 2.5V to 5.5V down to two independent, low-voltage outputs that are adjustable from 0.8V to 5V, making it an ideal choice for portable and battery-powered applications where space and power efficiency are critical.

Each channel of the LTC3407EMSE#TRPBF is capable of delivering up to 600mA of continuous output current, which ensures reliable performance for a wide range of electronic devices. The use of constant-frequency, current-mode architecture provides excellent line and load transient responses, while the low dropout operation ensures the maximum possible efficiency throughout the full range of load currents.

The LTC3407EMSE#TRPBF features internal switches with an RDS(ON) of only 0.35Ω, which contributes to its high efficiency, often exceeding 90%. This efficiency, combined with a quiescent current of just 20μA per channel, helps to maximize battery life in portable devices. Additionally, the device offers a selectable Burst Mode operation, which further reduces quiescent current down to just 15μA during light load conditions.

For added flexibility, the LTC3407EMSE#TRPBF includes a power good output, independent shutdown controls, and a 1MHz fixed frequency operation which allows for the use of small surface mount inductors and capacitors, reducing the overall footprint of the power supply design. Over-temperature and over-current protection are built-in features that enhance the safety and reliability of the application.

This dual DC/DC converter is available in a compact 10-lead MSOP package, which is RoHS compliant and suitable for a wide range of applications, including handheld devices, digital cameras, and other portable consumer electronics where efficient power management is essential.

Overall, the LTC3407EMSE#TRPBF is a robust and versatile power solution that offers designers the performance and features needed for today's power-sensitive and space-constrained electronic devices.
