LT3463EDD#PBF

Overview

The LT3463EDD#PBF is a dual-output switching regulator IC designed for generating positive and negative voltages from a single input source. It operates with an input voltage range of 2.4 V to 15 V and provides adjustable outputs ranging from ±1.25 V to ±40 V. The device integrates boost and charge pump topologies to achieve dual-rail regulation. It features two independent output channels capable of delivering up to 180 mA and 320 mA during switching operations. The component is housed in a compact 10-WFDFN package with an exposed pad, suitable for surface-mount installation.

Feature Summary

• Integrates boost and charge pump topology for simultaneous positive and negative voltage generation
• Provides dual independent adjustable output rails within specified voltage limits
• Supports wide input voltage operation from low battery levels up to 15 V

Applications

• Systems requiring dual power supplies from a single input source
• Portable electronic devices utilizing low-voltage batteries
• Circuits needing symmetric positive and negative voltage rails

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the 10-WFDFN package dimensions match your PCB footprint requirements. Ensure the input voltage does not exceed the 15 V maximum rating during operation. Check for availability through authorized Analog Devices distributors as supply status may vary.

Selection Notes

Select this component when dual-rail regulation is required from a single input without external transformers. Compare output current capabilities against load requirements to ensure adequate headroom. Consider the thermal performance of the DFN package for your enclosure design. Verify that the adjustable output range covers your specific application voltage needs.

Part Context

This part belongs to the LT3463 series of dual-output converters manufactured by Analog Devices. It is distinct from other regulators by its integrated ability to generate both positive and negative outputs simultaneously. The series is designed for applications where space constraints and single-input efficiency are critical factors.

Replacement Considerations

LT3463AEDD#PBF is a confirmed substitute within the same product family.
