LT3463EDD#TRPBF

Overview

The LT3463EDD#TRPBF is a dual-output switching regulator featuring boost and charge pump topologies, manufactured by Analog Devices Inc. It operates within an input voltage range of 2.4 V to 15 V and provides adjustable positive and negative outputs ranging from ±1.25 V to ±40 V. The device delivers up to 180 mA on the positive rail and 320 mA on the negative rail. Packaged in a 10-lead WDFN with exposed pad, it supports surface-mount installation and functions across a temperature range of 0°C to 70°C.

Feature Summary

• Integrates boost converter and charge pump circuits for simultaneous positive and negative voltage generation
• Provides independent current capabilities for each output rail to support asymmetric load requirements
• Features adjustable output voltages allowing flexible configuration for various system power needs

Applications

• Systems requiring dual polarity power supplies from a single source
• Op-amp biasing circuits needing symmetric positive and negative rails
• Interface drivers requiring separate supply voltages for logic and signal levels

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required thermal performance characteristics for the intended application environment. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and compliance with current manufacturing standards.

Selection Notes

Select this component when designing circuits that require both positive and negative regulated voltages from a single unregulated input source. Consider the maximum output current limits of 180 mA and 320 mA to ensure adequate headroom for the target loads. Evaluate the thermal dissipation requirements associated with the WDFN package under expected operating conditions.

Part Context

This part belongs to the LT3463 family of dual-output regulators designed for compact power solutions. It combines boost and charge pump technologies to generate dual rails efficiently. The series targets applications needing isolated or separated power domains without requiring multiple discrete converters or complex transformer-based designs.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternative part numbers. Do not assume functional equivalence with other dual-output regulators without verifying pin compatibility and electrical parameter alignment.
