LT3380IUJM#TRPBF

Overview

The LT3380IUJM#TRPBF is a multi-output power management integrated circuit manufactured by Analog Devices Inc. It integrates four buck switching regulators and three low-dropout (LDO) linear regulators within a single QFN-40 package. The device supports an input voltage range of 1.7 V to 5.5 V, with output currents rated at 300 mA, 1.5 A, and 2.5 A depending on the specific regulator channel. It features I2C control for configuration and operates across a temperature range of -40°C to +150°C.

Feature Summary

• Integrates four independent buck switching regulators and three LDO linear regulators in a compact form factor
• Provides digital control and monitoring capabilities via an I2C interface
• Supports wide input voltage ranges suitable for various battery and bus-powered applications

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Industrial equipment with space-constrained power architectures
• Communication infrastructure utilizing I2C-configurable power supplies

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure the operating temperature grade matches the design requirements, as industrial variants may differ from extended or military grades. Cross-reference the datasheet revision history to validate pin compatibility and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a high-density solution combining both switching and linear regulation is required. The I2C interface allows for dynamic adjustment of output voltages and monitoring of system status. Consider the thermal performance of the QFN-40 package relative to the total power dissipation of all active channels under maximum load conditions.

Part Context

This part belongs to the LT3380 series of multi-output power management ICs designed for complex embedded systems. It consolidates multiple discrete power components into a single chip to reduce board space and simplify design complexity. The integration of both switching and LDO regulators allows for optimized efficiency and noise performance across different subsystem loads.
