Overview
The LT3653EDCB#TRPBF is a high-voltage input switching regulator manufactured by Analog Devices Inc. It features an integrated 1.2A power switch and operates with an input voltage range from 7.5V to 30V. The device utilizes current-mode control with pulse width modulation for stable regulation. It includes built-in output current limiting, making it suitable for battery charger applications. The component is housed in an 8-pin HVSON package and supports operation temperatures from -40°C to +125°C.
Feature Summary
- Integrates a high-voltage 1.2A power switch for compact design
- Provides adjustable output voltage via external resistor network
- Includes internal output current limit protection
- Operates efficiently across wide input voltage ranges
Applications
- Battery charger systems
- High-voltage step-down conversion
- Industrial power supplies
Procurement Notes
Verify the exact suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records. Cross-reference the full part number against the latest datasheet revision to confirm pinout and electrical specifications match the design requirements.
Selection Notes
Select this component when a high input voltage capability up to 30V is required alongside moderate output current. The integrated switch reduces external component count compared to controller-based solutions. Consider the thermal performance of the HVSON package for the specific PCB layout. Verify that the application does not exceed the maximum junction temperature limits under worst-case load conditions.
Part Context
This part belongs to the LT3653 family of high-voltage buck regulators. It shares architectural similarities with other ADI high-voltage converters but is distinct in its fixed 1.2A current rating and specific input voltage window. It serves as a solution for applications requiring isolation between high input rails and lower output voltages without using magnetic components.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may differ in thermal resistance or switching frequency characteristics.
