LTC1702CGN

DC DC Switching Controllers Overview

The LTC1702CGN is a dual synchronous switching regulator controller designed for high-efficiency DC-DC conversion. It integrates two independent phase controllers operating at a fixed 550kHz switching frequency, enabling the generation of multiple output voltages from a single input source. The device supports an input voltage range of 3V to 7V and features a 24-lead SSOP package. It is optimized for applications requiring precise regulation of dual rails, such as providing 1.8V at 10A and 3.3V at 3A from a 5V logic supply.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture with independent control loops for simultaneous multi-rail regulation
• Synchronous buck topology integration for enhanced power efficiency
• Fixed 550kHz switching frequency operation for compact passive component sizing

DC DC Switching Controllers Applications

• Generating dual output voltages (e.g., 1.8V and 3.3V) from a single 5V logic supply
• High-current point-of-load regulation in computing systems
• Multi-rail power distribution networks requiring synchronized phase control

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature rating. Ensure the part number matches the required lead-free or RoHS compliance status if mandated by your assembly process. Cross-reference the datasheet revision date to confirm pinout compatibility with existing PCB layouts before procurement.

DC DC Switching Controllers Selection Notes

Select this controller when dual isolated outputs are required from a single input rail without using separate discrete controllers. It is suitable for designs needing fixed-frequency operation at 550kHz to minimize inductor size. Consider thermal management requirements for the SSOP-24 package when designing for continuous high-current loads up to 10A per phase.

DC DC Switching Controllers Part Context

This component belongs to the LTC1702 family of dual synchronous switching regulator controllers manufactured by Linear Technology, now part of Analog Devices. The CGN suffix denotes the commercial temperature range and SSOP-24 package variant. It serves as a core power management IC for systems requiring efficient dual-rail power delivery from standard logic voltage levels.

DC DC Switching Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative controllers only through direct electrical parameter comparison and pinout analysis against official manufacturer cross-reference lists.
