Overview
The LT8609AJDDM-5#PBF is a synchronous step-down switching regulator from Analog Devices, housed in a 10-lead DFN package. It delivers a fixed 5V output with a continuous current of 2A and a peak capability of 3A. The device supports an input voltage range from 3V to 42V. Key electrical parameters include a quiescent current of 2.5µA and an adjustable switching frequency between 200kHz and 2.2MHz. It operates within a temperature range of -40°C to +150°C junction temperature.
Feature Summary
- Integrates Silent Switcher 2 architecture with internal input capacitors to minimize electromagnetic interference radiation.
- Features a compact design utilizing an integrated ground plane and copper pillars instead of bonding wires for thermal efficiency.
- Includes a shutdown pin for power management control.
Applications
- Industrial systems requiring high-efficiency power conversion
- Automotive electronics operating within wide input voltage ranges
- Telecommunications infrastructure power supplies
Procurement Notes
Verify the specific suffix against official documentation, as ordering codes determine packaging and functional variations. Confirm availability status directly with the manufacturer or authorized distributors, as supply constraints may apply. Ensure the selected variant matches the required output voltage and package type for your design.
Selection Notes
Select this component when a fixed 5V output is required alongside high input voltage tolerance up to 42V. Consider the DFN-10 package for space-constrained layouts. Evaluate the trade-off between switching frequency and external component size based on the 200kHz to 2.2MHz range.
Part Context
This part belongs to the LT8609 family of Silent Switcher regulators. These devices are designed for applications demanding low EMI and high efficiency. The AJDDM designation indicates a specific temperature grade and package configuration within the broader product line.
Replacement Considerations
LT8609AJDDM-5#TRPBF serves as the tape-and-reel alternative to the tube-packaged LT8609AJDDM-5#PBF. Verify that the functional specifications remain identical before substitution.
