DC DC Switching Controllers datasheet and documents for LTC1622CMS8#TRPBF
DC DC Switching Controllers Overview
The LTC1622CMS8#TRPBF is a constant frequency current mode step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2V to 9.8V and delivers up to 5A output current. The device features a fixed switching frequency of 550kHz and adjustable output voltage. It includes shutdown functionality, with quiescent current of 350µA and operating supply current of 270µA. Designed for SOIC-8 surface mount packaging, it supports temperatures from 0°C to +70°C.
DC DC Switching Controllers Feature Summary
- Implements constant frequency current mode control for stable regulation
- Integrates accurate undervoltage lockout circuitry for input protection
- Supports external shutdown control for power management flexibility
DC DC Switching Controllers Applications
- Point-of-load regulation in industrial systems
- Battery-powered equipment requiring efficient buck conversion
- General-purpose DC/DC step-down applications
DC DC Switching Controllers Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability for Analog Devices Inc. components. Cross-reference the full part number against manufacturer databases to avoid counterfeit or obsolete stock issues during procurement.
DC DC Switching Controllers Selection Notes
Select this component for designs requiring a 5A synchronous buck solution with current mode control. The 550kHz frequency balances efficiency and component size. Verify that the 2V minimum input voltage aligns with the source rail. Consider thermal performance in the SOIC-8 package for high-current loads.
DC DC Switching Controllers Part Context
This part belongs to the LTC1622 series of switching regulators. It functions as a dedicated controller rather than an integrated switch regulator, requiring external MOSFETs. The CMS8 designation specifies the commercial temperature grade and MSOP/SOIC-8 compatible package variant within the Analog Devices portfolio.
DC DC Switching Controllers Replacement Considerations
Direct substitutes include the LTC1622CS8#PBF for tube packaging variants. Other family members like the LTC1622 may offer similar electrical characteristics but differ in package type or shipping configuration.
