LTC3707IGN#PBF

DC DC Switching Controllers Overview

The LTC3707IGN#PBF is a high-efficiency, dual-phase synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 28 V and supports adjustable output voltages from 800 mV to 7 V. The device delivers up to 25 A of output current across two channels. It features a programmable switching frequency between 150 kHz and 300 kHz. The controller includes clock synchronization capabilities and operates within a temperature range of -40°C to +85°C. It is housed in a 28-lead SSOP package.

DC DC Switching Controllers Feature Summary

• Dual-phase synchronous buck topology for high-current delivery
• Clock synchronization capability for system-wide noise management
• Programmable switching frequency allows optimization for efficiency or size

DC DC Switching Controllers Applications

• Industrial equipment power distribution
• Telecommunications infrastructure systems
• Point-of-load regulation for processors and FPGAs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the SSOP-28 package dimensions match the target PCB footprint. Ensure the design supports the required thermal dissipation for the 25 A output capability. Check for any recent PCN updates regarding manufacturing site changes.

DC DC Switching Controllers Selection Notes

Select this component when dual independent outputs are required from a single controller IC. It is suitable for applications needing wide input voltage ranges up to 28 V. Consider the external MOSFET selection carefully to achieve the specified 25 A performance. Evaluate the need for clock synchronization if multiple converters operate in proximity.

DC DC Switching Controllers Part Context

This part belongs to the LTC3707-SYNC series of high-performance DC/DC controllers. It is designed to replace older multi-controller solutions by integrating dual phases into a single package. The device complements other Analog Devices PMICs by providing robust control for heavy-load applications requiring precise voltage regulation.

DC DC Switching Controllers Replacement Considerations

LTC3707EGN#PBF offers identical electrical specifications but utilizes a tape-and-reel packaging format instead of tubes.
