LTC3707EGN#TRPBF

DC DC Switching Controllers Overview

The LTC3707EGN#TRPBF 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 delivers up to 25 A of output current across two independent channels. The adjustable output voltage spans from 800 mV to 7 V, supporting various low-voltage digital loads. The device features a programmable switching frequency between 150 kHz and 300 kHz. It includes integrated bootstrap diodes and requires only external N-channel MOSFETs. The component is housed in a 28-lead SSOP package and is designed for operation within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture enables high current delivery with reduced input and output ripple currents.
• Integrated bootstrap diodes simplify the external bill of materials by eliminating discrete components.
• Programmable switching frequency allows optimization for efficiency or component size.
• Supports external clock synchronization for noise management in complex power systems.

DC DC Switching Controllers Applications

• Point-of-load regulation for high-performance processors and FPGAs
• Industrial equipment requiring robust dual-rail power distribution
• Telecommunications infrastructure power supplies
• Embedded systems with strict thermal and space constraints

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the EG grade designation aligns with the intended industrial operating temperature range of -40°C to +85°C. Ensure compatibility with the DC455A evaluation board if initial prototyping is planned. Cross-reference the manufacturer's latest documentation for any pinout revisions or RoHS compliance updates prior to finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when designing systems requiring dual isolated outputs from a single intermediate bus voltage. The 4.5 V minimum input voltage suits applications powered by standard 12 V or 24 V rails. Consider the 25 A per channel capability against the thermal performance of the chosen SSOP footprint and PCB layout. Evaluate the need for external synchronization versus internal oscillator jitter tolerance based on system EMC requirements.

DC DC Switching Controllers Part Context

This component belongs to the LTC3707 family of synchronous buck controllers, which are engineered for high-density power conversion. It serves as a successor to earlier single-phase designs by offering doubled current capacity through phase interleaving. The SSOP-28 package provides a compact solution compared to larger QFN alternatives while maintaining sufficient thermal dissipation for moderate load applications.
