Overview
The LT8619IDD#TRPBF is a synchronous monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range up to 60V and delivers a maximum output current of 1.2A. The device features a fixed 0.8V reference voltage and supports adjustable switching frequencies between 300 kHz and 2.2 MHz. It consumes only 6µA of quiescent current in standby mode. The component is housed in a 10-WFDFN exposed pad package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- High efficiency synchronous buck topology for compact power solutions
- Ultra-low quiescent current consumption for extended battery life
- Wide input voltage capability supporting high-voltage sources
- Integrated protection mechanisms for reliable operation
Applications
- Industrial automation control systems
- Battery-powered portable equipment
- Point-of-load regulation modules
- Automotive electronics subsystems
Procurement Notes
Verify the exact part number suffix against official Analog Devices documentation to ensure correct packaging and pinout configuration. Confirm that the supplier provides valid traceability and authenticity guarantees. Check for any specific handling requirements related to the exposed pad thermal design during assembly.
Selection Notes
Select this component when a high-voltage input buck converter with low static current is required. Ensure the application demands a switching frequency within the 300 kHz to 2.2 MHz range. Verify that the 1.2A output current meets the load requirements without exceeding thermal limits in the chosen enclosure.
Part Context
This device belongs to the LT8619 family of high-speed synchronous regulators. It shares core architectural features with other members like the LT8619IMSE variants, differing primarily in package type and thermal characteristics. The family targets applications requiring small form factors and high efficiency under varying load conditions.
Replacement Considerations
Direct substitutes include LT8619IDD#PBF and LT8619IMSE-5#PBF. Verify compatibility regarding package dimensions and thermal performance before substitution.
