LTC1702AIGN#PBF

DC DC Switching Controllers Overview

The LTC1702AIGN#PBF is a dual switching regulator controller optimized for high efficiency with low input voltages. It integrates two complete, on-chip, synchronous buck controllers capable of driving external N-channel MOSFETs. The device operates at a fixed 550kHz switching frequency and supports dual non-isolated outputs. It features a 24-lead SSOP package and utilizes voltage-mode control to manage power conversion in step-down DC/DC applications.

DC DC Switching Controllers Feature Summary

• Integrates two independent synchronous buck controllers on a single chip
• Optimized for high efficiency operation with low input voltage supplies
• Supports dual non-isolated output configurations from a single input source

DC DC Switching Controllers Applications

• Dual-output DC/DC step-down converters
• Systems requiring separate positive output rails from a common logic supply
• Industrial power distribution modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. 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's latest documentation for any updated pinout or electrical characteristics.

DC DC Switching Controllers Selection Notes

Select this component when designing systems that require two isolated or non-isolated regulated outputs from a single low-voltage input rail. It is suitable for applications needing synchronized or independent phase control for dual buck converters. Consider the thermal performance of the SSOP package and the external MOSFET selection for the target current loads.

DC DC Switching Controllers Part Context

This part belongs to the LTC1702 family of dual synchronous buck controllers. It is designed to replace older discrete solutions by integrating control loops for two channels. The device simplifies board layout and reduces component count compared to using two separate single-channel controllers.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers include LTC1702CGN#TRPBF, LTC1702CGN#PBF, and LTC1702IGN#PBF. Verify pin compatibility and electrical specifications before substitution.
