LT3048IDC-12#TRPBF

Overview

The LT3048IDC-12#TRPBF is a dual-output power management IC from Analog Devices, integrating a boost switching regulator and an LDO in a single DFN-8 package. It provides a fixed 12V output at 45mA from the linear regulator and a regulated boost output of 13.1V at 300mA. Operating with an input voltage range of 2.7V to 4.8V, it utilizes a 2.2MHz switching frequency. The device features low quiescent current and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-current boost converter and a precision LDO within a compact footprint
Provides independent regulation for bias generation and main load requirements
Supports wide input voltage ranges suitable for battery-powered applications

Applications

Bias generation for analog-to-digital converters
Power supply for sensor interfaces requiring multiple voltage rails
Portable instrumentation systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the DC-12 variant matches the required 12V fixed output specification. Ensure the DFN-8 thermal pad soldering process aligns with PCB layout guidelines. Check for RoHS compliance documentation prior to final procurement approval.

Selection Notes

Select this component when a combined boost and LDO solution is needed to save board space. The fixed 12V output simplifies design compared to adjustable variants. Consider the 300mA boost capability for driving moderate loads while the LDO handles sensitive circuitry. Verify that the 2.2MHz frequency fits EMI constraints.

Part Context

This part belongs to the LT3048 series, which combines a step-up converter and an LDO. It is designed to provide efficient power conversion from low input voltages. The IDC-12 designation specifies the industrial temperature grade and the fixed 12V output configuration.
