LT3380EUJM#TRPBF

Overview

The LT3380EUJM#TRPBF is a specialized Power Management IC (PMIC) from Analog Devices, designed for advanced portable application processor systems. It integrates four synchronous step-down DC/DC converters to supply power rails for cores, memory, I/O, and System-on-Chip (SoC) components. The device operates with input voltages ranging from 1.7 V to 5.5 V and supports output currents up to 2.5 A per converter. It features adjustable output voltages between 850 mV and 3.8 V, with switching frequencies of 1.12 MHz and 2.25 MHz. Packaged in a 40-lead QFN (6x6 mm) with exposed pad, it functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates four synchronous buck converters for comprehensive multi-rail power management
• Supports I2C interface for programmable control and monitoring
• Optimized for low-power portable application processor systems

Applications
