Overview
The LT1170CK is a monolithic high-power switching regulator from Analog Devices Inc., housed in a TO-3-4 package. It integrates a high-current, high-efficiency switch with all necessary oscillator, control, and protection circuitry on the die. The device operates as a DC-to-DC converter with an input voltage range of 3V to 60V and supports output voltages up to 40V. It delivers an output current of 5A and provides up to 100W of output power. The component functions at a switching frequency of 100kHz.
Feature Summary
- Integrates a high-current, high-efficiency power switch with complete oscillator, control, and protection circuitry on a single die
- Supports operation in all standard switching configurations including buck, boost, flyback, forward, inverting, and Cuk topologies
- Designed for high-power applications with integrated thermal management capabilities inherent to the package
Applications
- Buck (step-down) converter circuits
- Boost (step-up) converter circuits
- Flyback converter designs
- Forward converter implementations
- Inverting and Cuk topology power supplies
Procurement Notes
Verify the specific suffix 'CK' against the official Analog Devices datasheet to confirm pinout compatibility and package type. Ensure the source document explicitly lists LT1170CK as a distinct part number rather than a generic family designation. Confirm that the TO-3-4 package matches your board layout requirements before procurement.
Selection Notes
Select this component when a monolithic solution is required for high-power DC-DC conversion up to 100W. It is suitable for designs needing flexibility across multiple standard switching topologies without external discrete switches. Consider the TO-3-4 package constraints for thermal dissipation and physical footprint in the final enclosure design.
Part Context
The LT1170 series represents a line of high-efficiency switching regulators originally developed by Linear Technology, now part of Analog Devices Inc. These devices are engineered to simplify power supply design by integrating the power switch and control logic. The CK variant specifically denotes the package configuration and manufacturing lot details within the broader LT1170 product family.
Replacement Considerations
Publicly confirmed substitute part numbers for LT1170CK are not available in the provided documentation. Consult Analog Devices official resources for cross-reference data or compatible alternatives within the same product family.
