LT3048EDC-12#TRPBF

Overview

The LT3048EDC-12#TRPBF is a dual-output power management IC from Analog Devices, integrating a 2.2 MHz synchronous boost converter and a low-dropout (LDO) regulator within an 8-pin DFN package. The boost stage provides a fixed 13.1 V output at up to 300 mA, while the LDO delivers a fixed 12 V output at 45 mA. It operates from a 2.7 V to 4.8 V input supply and supports junction temperatures from -40°C to +125°C.

Feature Summary

• Integrates a synchronous boost converter and an LDO regulator in a single compact package
• Provides two independent regulated outputs for bias generation and system powering
• Features high-frequency switching operation to minimize external passive component size

Applications

• Bias voltage generation for analog-to-digital converters
• Powering mixed-signal circuits requiring isolated or distinct voltage rails
• Portable equipment with limited board space constraints

Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the specific voltage variant matches design requirements, as the LT3048 series includes multiple fixed output options. Ensure compatibility with the 8-DFN thermal pad soldering process for optimal heat dissipation.

Selection Notes

Select this part when a combined boost and LDO solution is needed from a single-cell lithium battery source. The fixed 12 V LDO output simplifies design compared to adjustable variants. Verify that the 300 mA boost current capability meets the total load demand of the downstream circuitry.

Part Context

This component belongs to the LT3048 family of dual step-up/boost switching and LDO regulators. It is designed to replace discrete solutions, reducing bill of materials and assembly complexity. The device is manufactured by Analog Devices Inc. under the LT brand.

Replacement Considerations

LT3048EDC-12#TRMPBF offers identical electrical specifications but in cut-tape packaging instead of reel.
