LT3048EDC#TRMPBF

Voltage Regulators - Linear + Switching Overview

The LT3048EDC#TRMPBF is a dual-output power management IC from Analog Devices, combining a boost switching regulator with an LDO. It operates within a 2.7V to 4.8V input voltage range and features a 2.2MHz switching frequency. The device provides two outputs: Output 1 delivers up to 300mA at voltages ranging from 5V to 16.1V, while Output 2 supplies up to 45mA at fixed voltages including 5V, 12V, or 15V. Packaged in an 8-DFN (2x2) surface-mount format, it supports industrial temperatures from -40°C to +125°C.

Voltage Regulators - Linear + Switching Feature Summary

• Integrates a high-efficiency synchronous boost converter with a low-noise LDO regulator for comprehensive power generation.
• Provides independent control over the boost output voltage via external resistors while maintaining precise regulation on the secondary LDO channel.
• Features a compact 8-lead DFN package designed for space-constrained applications requiring dual-rail power solutions.

Voltage Regulators - Linear + Switching Applications

• Powering mixed-signal systems requiring separate noise-sensitive and standard rails
• Embedded sensor nodes with limited input voltage headroom

Voltage Regulators - Linear + Switching Procurement Notes

Verify the specific suffix designation when ordering, as variants such as LT3048EDC-5#TRMPBF or LT3048IDC-15#TRMPBF indicate different fixed output configurations for the LDO channel. Confirm that the base part number LT3048EDC#TRMPBF corresponds to the adjustable boost and configurable LDO version required by your schematic. Ensure compatibility with the 8-DFN footprint during procurement validation.

Voltage Regulators - Linear + Switching Selection Notes

Select this component when a single IC must generate both a higher-voltage rail from a lower source and a clean, regulated auxiliary supply. The dual topology eliminates the need for separate discrete regulators, reducing board area. Consider the maximum output current limits of 300mA and 45mA against your load requirements to ensure adequate thermal performance within the specified operating temperature range.

Voltage Regulators - Linear + Switching Part Context

This part belongs to the LT3048 series, which specializes in dual-output power management solutions. The series combines switching efficiency with linear regulation precision. The EDI suffix typically denotes the extended industrial temperature grade and specific pinout configuration compatible with standard 8-DFN layouts used in modern consumer and industrial electronics.

Voltage Regulators - Linear + Switching FAQ

What is the difference between the LT3048EDC and LT3048IDC suffixes?

The 'E' suffix indicates an extended industrial temperature range (-40°C to +125°C), while the 'I' suffix typically denotes a commercial temperature range. Verify the specific datasheet for the exact thermal specifications of your variant.

Can the boost output voltage be adjusted independently of the LDO output?

Yes, the boost output voltage is set by external resistors and can be adjusted independently. The LDO output voltage is determined by its specific model suffix (e.g., -5 for 5V) or external feedback network depending on the exact sub-part.
