Overview
The LT1683IG#PBF is a switching regulator controller manufactured by Analog Devices Inc., designed to minimize conducted and radiated electromagnetic interference. It utilizes a push-pull topology with a single output, operating within an input voltage range of 4 V to 20 V. The device provides a fixed 5 V output at 10 mA and features a low static current of 24 uA. It supports a switch frequency between 20 kHz and 250 kHz and operates in temperatures from -40 C to +125 C. Packaged in a 20-SSOP format for surface mount installation.
Feature Summary
- Slew rate controlled architecture for ultralow noise and EMI reduction
- Push-pull DC/DC controller topology for step-up and step-down applications
- Integrated shutdown functionality for power management
Applications
- Electromagnetic interference sensitive power systems
- Ultralow noise DC/DC conversion circuits
- Push-pull regulated power supply designs
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check lifecycle status as some listings indicate obsolete or limited availability. Ensure compliance with RoHS standards and verify shipping restrictions applicable to your region before finalizing procurement orders.
Selection Notes
Select this controller when minimizing electromagnetic interference is critical for system performance. The push-pull topology suits applications requiring both positive and negative outputs or specific transformer drive requirements. Consider the 20-SSOP package constraints and thermal characteristics for board layout. Verify that the 4 V to 20 V input range aligns with the target power source specifications.
Part Context
This component belongs to the LT1683 series of switching regulators. It is part of Analog Devices' portfolio of power management integrated circuits focused on noise reduction. The device serves as a specialized controller rather than a complete converter, requiring external switches and passive components to function.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Analog Devices resources for cross-reference data.
