LTC1702ACGN#PBF

DC DC Switching Controllers Overview

The LTC1702ACGN#PBF is a dual-phase synchronous switching regulator controller manufactured by Analog Devices Inc. It operates with a fixed 550kHz switching frequency and accepts an input voltage range of 3V to 7V. The device provides two non-isolated positive outputs, typically configured for 1.8V at 10A and 3.3V at 3A in evaluation setups. It utilizes a buck topology and is housed in a 24-SSOP package. The component is designed for high-efficiency DC/DC conversion, achieving up to 90% efficiency in standard applications.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture enabling independent control of two output channels
• Synchronous rectification for improved power conversion efficiency
• Fixed 550kHz switching frequency for optimized passive component size
• Integrated voltage-mode control loop stability

DC DC Switching Controllers Applications

• Generating dual rails from a single 5V logic supply
• Powering multi-voltage digital systems requiring 1.8V and 3.3V
• Embedded systems utilizing buck topology for step-down conversion
• Evaluation of dual-output DC/DC converter designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the 24-SSOP package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any recent product change notices affecting pinout or electrical characteristics.

DC DC Switching Controllers Selection Notes

Select this controller when dual isolated outputs are not required but independent phase control is beneficial for current sharing. It is suitable for applications needing a 3V to 7V input range. Consider the 550kHz frequency trade-off between component size and switching losses. Verify that the external MOSFETs selected can handle the expected current loads for both phases without exceeding thermal limits.

DC DC Switching Controllers Part Context

This component belongs to the LTC1702 family of dual-phase switching regulators. It serves as a controller IC rather than a complete integrated power stage, requiring external MOSFETs and passive components. The device is part of Analog Devices' portfolio for efficient DC/DC conversion solutions in portable and industrial electronics.

DC DC Switching Controllers Replacement Considerations

LTC1702CG#TRPBF is a direct functional substitute within the same family. Both devices share identical electrical characteristics and pinouts. The primary difference lies in packaging; the TRPBF variant uses tape and reel while the PBF uses tubes. Verify compatibility with existing board layouts before substitution.
