LTC1702CGN

DC DC Switching Controllers Overview

The LTC1702CGN is a dual-phase synchronous switching regulator controller designed for high-efficiency DC-DC conversion. It operates from a 3V to 7V supply and features a fixed 550kHz switching frequency. The device supports two independent outputs, enabling configurations such as generating 1.8V at 10A and 3.3V at 3A from a single 5V input. With a typical efficiency of 90%, it utilizes a buck topology. The component is housed in a 24-lead SSOP package and functions within an ambient temperature range of 0°C to 70°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., #PBF vs #TRPBF) against the required packaging format, as these denote different shipping units rather than functional differences. Confirm the lifecycle status, as this model may be marked obsolete by the manufacturer. Ensure the operating temperature range meets the environmental requirements of the final assembly before procurement.

DC DC Switching Controllers Selection Notes

Select this controller when dual isolated or non-isolated outputs are required from a single phase-shifted or interleaved control scheme. It is suitable for applications demanding high current density where synchronous rectification improves overall system efficiency. Consider the 24-lead SSOP package constraints regarding thermal dissipation and PCB layout space compared to larger packages.

DC DC Switching Controllers Part Context

The LTC1702 belongs to Analog Devices' family of synchronous buck controllers. It is engineered to drive external N-channel MOSFETs for efficient power regulation. The CGN variant specifically denotes the commercial temperature grade and narrow SSOP package. This component serves as a core power management element in systems requiring precise multi-voltage generation.
