LT3482EUD#PBF

Overview

The LT3482EUD#PBF is a monolithic boost DC/DC converter designed for high-voltage applications, featuring an integrated avalanche photodiode (APD) current monitor. It operates from an input voltage range of 2.5V to 16V and provides an adjustable output voltage up to 90V. The device incorporates a 280mA switch with a selectable switching frequency between 650kHz and 1.1MHz. Packaged in a 16-lead QFN with an exposed pad, it supports positive single-output configuration.

Feature Summary

• Integrated APD current monitor for precise bias control
• Adjustable output voltage capability up to 90V
• Selectable switching frequency for optimization

Applications

• Avalanche photodiode bias supply
• High voltage boost conversion
• Optical detection systems

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing ordering information. Confirm the lead-free status and RoHS compliance details against the manufacturer's latest documentation. Ensure the 16-pin QFN footprint matches the design requirements before finalizing procurement.

Selection Notes

Select this component when an internal switch is required for boost applications exceeding standard regulator limits. The integrated APD monitor simplifies circuit design for optical sensors. Consider the thermal performance of the exposed pad layout for efficient heat dissipation during operation.

Part Context

This part belongs to the LT3482 family of high voltage boost converters. It is distinct from other Analog Devices regulators by its specific focus on APD monitoring integration. The EUD variant specifies the 16-lead QFN package type within the product line.
