Overview
The LT1506CR#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with a fixed 500 kHz switching frequency and supports an input voltage range of 4.5 V to 15 V. The device provides an adjustable output voltage and delivers up to 4.5 A of output current. It utilizes a DPAK-7 package for surface-mount installation.
Feature Summary
- Integrates a synchronous power switch for high efficiency in a compact footprint
- Features internal compensation to minimize external component count
- Includes thermal shutdown protection for enhanced reliability
Applications
- Battery-powered portable equipment
- Distributed power systems
- Post-regulation for bus supplies
Procurement Notes
Verify the exact part number against official Analog Devices documentation, as suffixes define specific packaging or temperature grades. Confirm RoHS compliance status directly from the manufacturer's datasheet. Ensure the supplier provides valid traceability documents. Cross-reference the date code to verify manufacturing recency. Validate that the component matches the specified DPAK-7 package dimensions.
Selection Notes
Select this component when a high-current buck converter is required with minimal external parts. The fixed 500 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the input voltage range of 4.5 V to 15 V aligns with the system supply. Ensure the load current does not exceed the 4.5 A limit under all operating conditions.
Part Context
This part belongs to the LT1506 family of switching regulators designed for general-purpose DC/DC conversion. It serves as a cost-effective solution for medium-power applications requiring adjustable outputs. The family is known for integrating the power switch and control logic into a single monolithic chip.
FAQ
Is the LT1506CR#TRPBF available in a lead-free package?
Yes, the #TRPBF suffix indicates a Pb-free (lead-free) tape and reel packaging option compliant with RoHS standards.
What is the maximum switching frequency of the LT1506?
The LT1506 operates at a fixed switching frequency of 500 kHz.
