LT3048IDC-3.3#TRMPBF

Overview

The LT3048IDC-3.3#TRMPBF is a power management integrated circuit manufactured by Analog Devices Inc., housed in an 8-WFDFN package with an exposed pad. It integrates a boost regulator and a low-dropout linear regulator to generate low noise, low ripple bias supplies from input voltages ranging from 2.7V to 4.8V. The device features two outputs: Output 1 provides 4.4V at up to 300mA, while Output 2 delivers a fixed 3.3V at up to 45mA. It operates within a temperature range of -40°C to +125°C and includes shutdown functionality.

Feature Summary

• Integrates a boost converter and a linear regulator for efficient bias generation
• Provides low noise and low ripple output capabilities
• Supports wide operating temperature ranges suitable for industrial applications

Applications

• Low noise bias supply generation for sensitive analog circuits
• Industrial control systems requiring stable voltage rails
• Embedded systems needing compact power management solutions

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm the specific suffix #TRMPBF indicates tape and reel packaging compatible with automated assembly processes. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when a combined boost and LDO solution is required within a small footprint. Consider the 2.7V to 4.8V input range and the specific output current capabilities of 300mA and 45mA. Evaluate thermal performance given the DFN package and ensure the application benefits from the integrated shutdown feature for power optimization.

Part Context

This part belongs to the LT3048 series, which combines a boost regulator and an LDO linear regulator. It is designed to generate clean power from low input voltages. The IDC suffix denotes the DFN package type, while the 3.3#TRMPBF suffix specifies the fixed 3.3V output on the second channel and the tape and reel packaging format.

Replacement Considerations

LT3048IDC-15#TRPBF offers similar integration but with different output specifications (15V/45mA). LT3048IDC-3.3#TRPBF provides the same electrical characteristics but in cut-tape packaging instead of tape and reel. Verify pinout and thermal pad connections when substituting.
