LT3048IDC-15#TRPBF

Overview

The LT3048IDC-15#TRPBF is a dual-output power management IC from Analog Devices, combining a boost switching regulator with a low-noise linear regulator in an 8-lead DFN package. It operates within an input voltage range of 2.7 V to 4.8 V and features a fixed 15 V output on the second channel capable of delivering up to 45 mA. The primary boost channel provides a higher current capacity, while the device maintains a typical quiescent current of 475 uA. Designed for surface-mount installation, it supports operation across an extended temperature range from -40°C to +125°C with a switching frequency of 2.2 MHz.

Feature Summary

• Integrates a high-efficiency boost converter with a dedicated low-noise LDO in a single compact package
• Provides precise fixed output voltage regulation for bias generation applications
• Supports shutdown functionality to minimize power consumption during inactive states

Applications

• Bias generation for RF front-end modules
• Power supply for precision analog circuits requiring low noise
• Embedded systems requiring combined switching and linear regulation

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific suffix matches the required tape and reel packaging configuration. Ensure compliance with RoHS directives and check for any restricted substance declarations relevant to your manufacturing process. Validate that the received lot corresponds to the specified operating temperature grade and package variant.

Selection Notes

Select this component when a design requires both efficient step-up conversion and clean linear regulation within tight space constraints. Consider the 2.2 MHz switching frequency for EMI management and the specific output current capabilities of each channel. Evaluate thermal performance requirements given the small DFN footprint and ensure input voltage conditions remain within the specified operational window for stable regulation.

Part Context

This part belongs to the LT3048 series, which combines switching and linear technologies for efficient power management. It is distinct from other regulators by offering two independent outputs in one package. The IDC designation indicates the specific thermal and electrical characteristics of the DFN-8 package variant used for surface-mount assembly.
