LT3380IUJM#PBF

Overview

The LT3380IUJM#PBF is a specialized power management IC (PMIC) from Analog Devices, designed as a multi-output power solution with I2C control. It integrates four buck switching regulators and three LDO linear regulators within a single QFN-40 package. The device operates with an input voltage range of 1.7 V to 5.5 V. Output currents are specified at 300 mA, 1.5 A, and 2.5 A depending on the regulator channel. The maximum output voltage reaches 3.8 V, while the minimum operating voltage starts at 850 mV. Quiescent input current is 14 uA. It supports operation between -40 C and +150 C.

Feature Summary

• Integrates multiple power regulation stages including switching and linear regulators in a compact form factor
• Provides digital configuration and monitoring capabilities via I2C interface
• Supports wide input voltage ranges suitable for various system power rails

Applications

• Complex embedded systems requiring multiple regulated voltage rails
• Industrial control units with digital management needs
• Communication equipment needing efficient power distribution

Procurement Notes

Verify the specific suffix and tape/reel or tube packaging requirements against your assembly line specifications. Confirm that the I2C address and register map align with your system controller. Ensure thermal design accounts for the QFN-40 package dissipation characteristics under full load conditions across the specified temperature range.

Selection Notes

Select this component when a high degree of integration is required to reduce board space and component count. It is suitable for designs where digital control over power sequencing or monitoring is necessary. Consider the thermal performance and available PCB area for the QFN-40 footprint when finalizing the layout.
