LT3482IUD#PBF

Overview

The LT3482IUD#PBF is a high voltage boost DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5V to 16V and provides an adjustable output voltage up to 90V. The device integrates a power switch capable of delivering 280mA of current. It features a switching frequency that can be synchronized or adjusted between 650kHz and 1.1MHz. The component is housed in a 16-pin QFN package with an exposed pad.

Feature Summary

• Integrates a dedicated avalanche photodiode (APD) current monitor for precise bias control
• Supports external synchronization to reduce system noise
• Features adjustable switching frequency for optimization of passive component size

Applications

• Avalanche photodiode biasing circuits
• High voltage boost conversion systems
• Optical communication transceivers

Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free tin plating and RoHS compliance when sourcing. Confirm the 'I' grade designation matches the required industrial temperature range specifications for your application environment. Ensure the 16-pin QFN EP package footprint aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when an integrated APD monitor is required to simplify circuit design. Consider the 280mA switch current limit against peak load requirements. Evaluate the need for external synchronization to mitigate electromagnetic interference in sensitive environments compared to fixed-frequency alternatives.

Part Context

This part belongs to the LT3482 family of high voltage boost converters designed specifically for driving avalanche photodiodes. It distinguishes itself from standard boost regulators by including built-in monitoring capabilities for the photodiode current, reducing the need for external sensing components.
