LT3383EUJM#PBF

Overview

The LT3383EUJM#PBF is a multi-output power management integrated circuit from Analog Devices, designed for high-efficiency applications. It integrates four buck switching regulators and three low-dropout (LDO) linear regulators to provide eight distinct output voltages. The device operates with an input voltage range starting at 1.7 V and supports maximum output voltages up to 3.8 V. It utilizes a fixed switching frequency of 2.25 MHz for the buck converters. The component is housed in a 40-lead exposed pad WFQFN package and is rated for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates four step-down buck switching regulators and three LDO linear regulators within a single chip
• Designed as a specialized PMIC solution for automotive ADAS environments
• Supports wide input voltage ranges suitable for low-voltage power distribution

Applications

• Advanced Driver Assistance Systems (ADAS)
• Automotive power management solutions
• Multi-rail power distribution networks

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the package type matches the 40-lead WFQFN with exposed pad requirements for thermal management. Ensure the supplier provides valid RoHS documentation consistent with Analog Devices standards before finalizing procurement orders.

Selection Notes

Select this component when a consolidated power solution is required for systems needing multiple regulated rails from a single source. It is appropriate for designs where space constraints favor an integrated PMIC over discrete regulators. Consider the 2.25 MHz switching frequency for EMI management and the thermal capabilities of the exposed pad package for heat dissipation in enclosed automotive enclosures.

Part Context

This part belongs to the LT3383 family of high-efficiency, low-voltage PMICs developed by Analog Devices. These devices are engineered specifically for demanding automotive electronics, offering a compact alternative to discrete power stages. The EUJM variant denotes the specific package and temperature rating configuration within the broader product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices directly for qualified alternatives or pin-compatible replacements that meet identical electrical and thermal specifications.
