LT1506CR-3.3#TRPBF

Overview

The LT1506CR-3.3#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., housed in an 8-pin DDPAK package with a thermal pad. It operates within an input voltage range of 4V to 15V and provides a fixed output voltage of 3.3V at a maximum current of 4.5A. The device integrates a 4.5A power switch, oscillator, and control logic, functioning at a switching frequency of 500kHz. It is optimized for lower input voltage applications compared to the LT1374.

Feature Summary

Integrates a high-current 4.5A synchronous power switch for efficient step-down conversion
Optimized for low input voltage operation ranging from 4V to 15V
Includes internal oscillator, control circuitry, and logic for simplified design

Applications

5V to 3.3V step-down converter circuits
Low input voltage DC-DC conversion systems
General purpose synchronous buck regulation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix #TRPBF indicates tape-and-reel packaging with lead-free compliance. Cross-reference datasheet revisions to ensure compatibility with current design requirements. Check for obsolescence status as availability may be limited.

Selection Notes

Select this component when a fixed 3.3V output is required from a 4V to 15V input source. It serves as a functional alternative to the LT1374 but is specifically tailored for lower input voltage ranges. Ensure the application demands a 4.5A current capability and benefits from synchronous rectification efficiency.

Part Context

This part belongs to the LT1506 series of monolithic buck mode switching regulators. It shares functional similarities with the LT1374 but distinguishes itself through optimization for input voltages starting at 4V rather than 5.5V. The series is designed for applications requiring robust step-down regulation with integrated power switching capabilities.
