LT3500EDD#PBF

Overview

The LT3500EDD#PBF is a monolithic power management IC from Analog Devices, integrating a synchronous 2A step-down switching regulator with an adjustable linear regulator and controller. It operates within an input voltage range of 3V to 36V and supports two independent outputs. The device utilizes a fixed 2.2MHz switching frequency for the buck converter and features a DFN-12 package. Key electrical specifications include a maximum output current of 2A, an adjustable output voltage, and a quiescent current of 2.5mA. It functions reliably across an extended temperature range from -40°C to +150°C.

Feature Summary

• Integrates a high-efficiency synchronous buck converter with a dedicated linear regulator section
• Supports wide input voltage ranges suitable for automotive and industrial applications
• Includes integrated control circuitry for external linear regulation capabilities

Applications

• Automotive electronic systems requiring robust power conversion
• Industrial equipment with varying input supply voltages
• Embedded systems needing combined switching and linear regulation

Procurement Notes

Verify the specific suffix (EDD) against official datasheets to confirm package type and temperature grade. Ensure compatibility with required input/output configurations. Check for RoHS compliance status in the latest manufacturer documentation. Confirm availability through authorized distributors as stock levels fluctuate. Validate pinout alignment with PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a single solution is needed for both high-current switching and precision linear regulation. Consider the 2A capacity for primary loads and the linear section for noise-sensitive circuits. Evaluate thermal performance given the DFN-12 package constraints. Compare against standalone regulators if higher efficiency or lower quiescent current is critical for the specific application design.
