DC DC Switching Controllers datasheet and documents for LTC3701EGN#PBF

LTC3701EGN#PBF

DC DC Switching Controllers Overview

The LTC3701EGN#PBF is a dual constant frequency current mode step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.5V to 9.8V and provides two non-isolated outputs. The device supports switching frequencies up to 550kHz and delivers output currents of 1.6A per phase. It features synchronous rectification, clock synchronization, and control characteristics including overcurrent protection, enable functionality, frequency control, and soft start. The component is housed in a 16-SSOP package and is designed for surface mount installation.

DC DC Switching Controllers Feature Summary

Dual-phase architecture for enhanced power delivery
Constant frequency current mode operation
Synchronous rectification for improved efficiency
Integrated clock synchronization capability

DC DC Switching Controllers Applications

Single cell lithium-ion battery to 3.3V/1A converters
Single cell lithium-ion battery to 1.8V/2A converters
Low input voltage DC/DC conversion systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before procurement. Confirm the SSOP-16 package dimensions match your PCB footprint requirements. Ensure the input voltage range of 2.5V to 9.8V aligns with your system design constraints. Check for availability of evaluation boards like DC424A for initial testing.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring high efficiency from low input voltages such as single-cell Li-Ion sources. The dual-phase design allows for higher total output current compared to single-phase alternatives. Consider the 550kHz switching frequency when designing external inductors and capacitors. Verify thermal performance under maximum load conditions given the SSOP package.

DC DC Switching Controllers Part Context

This component belongs to the LTC3701 series of dual DC/DC controllers. It is distinct from the LTC3703, which is a buck-boost controller with different topology and input voltage ranges. The LTC3701 focuses on step-down conversion for portable electronics powered by single-cell batteries.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other dual-phase buck controllers from Analog Devices or competitors based on pin compatibility and electrical specifications if direct substitution is required.
