LT3048IDC

Overview

The LT3048IDC is a dual-output power management IC from Analog Devices, integrating a high-efficiency boost switching regulator and a low-noise LDO in an 8-lead DFN package. It operates with an input voltage range of 2.7V to 4.8V and features a fixed 2.2MHz switching frequency. The device provides two independent outputs: Output 1 delivers up to 300mA at voltages ranging from 5V to 16.1V, while Output 2 supplies up to 45mA at voltages from 5V to 15V. Designed for industrial temperatures between -40°C and +125°C, it includes shutdown functionality and requires minimal external components.

Feature Summary

Integrates a high-efficiency boost converter and a low-noise LDO within a single compact package
Provides two independent regulated outputs for simultaneous bias generation
Features a fixed 2.2MHz switching frequency to minimize passive component size
Includes shutdown control for enhanced system power management

Applications

Dual-rail bias generation for analog-to-digital converters (ADCs)
Power supply systems for portable instrumentation
Industrial sensor interface circuits requiring clean power rails
Embedded systems with mixed-signal requirements

Procurement Notes

Verify the specific suffix (e.g., #TRPBF, #TRMPBF) to confirm packaging type and RoHS compliance status. Confirm availability as distribution channels may list limited stock or backorder statuses. Ensure the selected variant matches the required thermal performance for the target application environment.

Selection Notes

Select based on required output current capabilities and voltage ranges for each rail. Consider the 8-DFN package for space-constrained designs. Evaluate thermal dissipation requirements given the 300mA boost output capability. Verify compatibility with the 2.7V to 4.8V input voltage range of the host system.

Part Context

Part of the LT3048 series, which combines switching and linear regulation technologies. This family targets applications needing multiple clean power rails from a single low-voltage source. The DC2258A evaluation board is available for testing boost configuration performance.
