LT3500HDD#PBF

Overview

The LT3500HDD#PBF is a monolithic power management IC integrating a 2A synchronous buck regulator and a linear regulator/controller. It operates from an input voltage range of 3V to 36V with a switching frequency of 2.2MHz. The device provides two outputs: a high-current adjustable buck output and a separate linear output. It features a low quiescent current of 2.5mA and supports shutdown functionality. Packaged in a 12-lead DFN, it is designed for automotive applications with an operating temperature range of -40°C to +150°C.

Feature Summary

Integrates a 2A synchronous step-down converter with a dedicated linear regulator controller on a single die.
Supports wide input voltage ranges suitable for automotive systems with load dump conditions.
Features a high switching frequency to minimize external passive component size.
Includes thermal protection and shutdown control for system power management.

Applications

Automotive infotainment systems requiring multiple regulated rails
Industrial control modules with wide input voltage variations
Distributed power architectures needing compact DC-DC conversion

Procurement Notes

Verify the specific suffix (HDD) against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the package type matches the PCB footprint requirements. Confirm RoHS compliance status through the latest manufacturing documentation before integration into production designs.

Selection Notes

Select this component when a combined buck and linear solution is required within a small form factor. Consider the 2A current limit for the primary output and the input voltage range constraints. Evaluate thermal performance based on the expected power dissipation in the DFN-12 package under maximum load conditions.

Part Context

This part belongs to the LT3500 family of mixed-signal power management ICs. It combines switching and linear technologies to simplify board layout and reduce component count compared to discrete solutions. The family targets applications requiring robust power regulation in space-constrained environments.
