LT3663EDCB-3.3#TRPBF

Overview

The LT3663EDCB-3.3#TRPBF is a current-mode step-down switching regulator manufactured by Analog Devices Inc., housed in an 8-lead DFN package. It features a wide input voltage range of 7.5V to 36V and delivers up to 1.2A of output current. The device provides a fixed 3.3V output and incorporates programmable output current limiting for precise system power dissipation control. Operating at a 1.5MHz switching frequency, it utilizes synchronous rectification to maximize efficiency while minimizing external component size.

Feature Summary

Integrates programmable output current limit to accurately control system power dissipation
Utilizes synchronous rectification topology for high efficiency across load ranges
Features a compact 8-lead DFN surface-mount package design

Applications

Typical application as a 3.3V step-down converter
Powering systems requiring controlled power dissipation limits
Applications utilizing the DC1570A demonstration board for evaluation

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct output voltage and thermal characteristics. Confirm that the requested part matches the required operating temperature range and packaging specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3V output is required from a 7.5V to 36V input source. The integrated current limit feature makes it suitable for designs needing precise power management without additional sensing circuitry. Consider the 1.5MHz frequency for balancing component size against electromagnetic interference requirements compared to lower-frequency alternatives.

Part Context

This part belongs to the LT3663 series of monolithic synchronous buck regulators. It shares architectural similarities with other devices in the family but is distinguished by its specific 3.3V fixed output configuration and 1.2A current rating. The series is designed for applications demanding small solution sizes and robust protection features within a compact footprint.
