Overview
The LT3992EFE#TRPBF is a monolithic dual tracking 3A step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 60V and provides two adjustable positive outputs, each capable of delivering up to 3A. The device features a wide switching frequency range from 110kHz to 2.5MHz and supports output voltages starting from 0.8V. Packaged in a 38-TFSOP with an exposed pad for thermal management, it functions within a junction temperature range of -40°C to 150°C.
Feature Summary
- Monolithic dual-channel architecture enabling independent or synchronized tracking control
- Wide input voltage compatibility supporting diverse power supply sources
- Integrated thermal performance via exposed pad package design
Applications
- Industrial equipment requiring dual regulated rails
- Telecommunications infrastructure power systems
- Automotive electronics power distribution
Procurement Notes
Verify the specific suffix EFE#TRPBF against official Analog Devices documentation to confirm the 38-TSSOP-EP package and reel packaging configuration. Ensure the ordering part number matches the exact electrical specifications required for your circuit design before procurement.
Selection Notes
Select this component when dual isolated or tracked low-voltage high-current outputs are needed from a higher voltage bus. Evaluate the thermal requirements of the TSSOP-EP package against your PCB layout capabilities. Confirm that the required output voltage range falls within the 0.8V minimum specification.
Part Context
This part belongs to the LT3992 family of dual synchronous buck converters. It is designed for applications requiring compact solutions with high efficiency. The device integrates power switches and control logic into a single chip to minimize external component count.
Replacement Considerations
Consult official Analog Devices cross-reference lists for verified substitutes. Generic equivalents may not support the dual tracking functionality or the specific 3A per channel current rating.
