Overview
The LT3571EUD#TRPBF is a current mode step-up DC/DC converter manufactured by Analog Devices Inc. It features an integrated Schottky diode and supports an input voltage range of 2.7 V to 20 V. The device provides a positive adjustable output voltage up to 75 V with a switch current capability of 370 mA. Operating supply current is 1.7 mA, and it includes a shutdown function. The component is housed in a 16-WFQFN Exposed Pad package.
Feature Summary
- Current mode step-up DC/DC converter architecture
- Integrated high-voltage Schottky diode
- Adjustable output voltage capability
- Low operating supply current
Applications
- Avalanche photodiode (APD) biasing
- PIN diode biasing
- Optical receiver modules
- Fibre optic network equipment
Procurement Notes
Verify the complete part number including suffixes such as TRPBF against official Analog Devices documentation to ensure correct packaging and environmental compliance. Confirm that the 16-WFQFN Exposed Pad package matches your PCB footprint requirements. Cross-reference electrical specifications like the 75V maximum output and 370mA switch current with your system design constraints before procurement.
Selection Notes
Select this component for applications requiring precise bias voltages for optical detectors. Ensure the input voltage source stays within the 2.7 V to 20 V range. Consider the thermal performance of the exposed pad QFN package for heat dissipation. Verify that the required output voltage does not exceed the 75 V limit and that the load current remains within the 370 mA internal switch rating.
Part Context
This part belongs to the LT3571 family of high-reliability DC/DC converters designed specifically for precision APD bias applications. The EUD#TRPBF designation indicates the specific package type and tape-and-reel packaging format. It serves as a dedicated solution for powering avalanche photodiodes in sensitive optical communication systems where stable bias voltage is critical.
Replacement Considerations
The LT3571EUD#PBF is a publicly confirmed substitute offering identical electrical characteristics but in a tube package instead of tape-and-reel. Ensure the mechanical footprint compatibility between the QFN packages if swapping packaging formats.
