LT3048IDC-5

Overview

The LT3048IDC-5#TRMPBF is a dual-output power management IC from Analog Devices, combining a boost switching regulator and an LDO in an 8-lead DFN package. It operates with an input voltage range of 2.7V to 4.8V at a fixed 2.2MHz switching frequency. Output 1 provides up to 300mA at 6.1V, while Output 2 delivers 45mA at 5V. The device supports shutdown functionality and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-efficiency boost converter and a low-noise LDO regulator for comprehensive power generation.
Features a compact 8-lead DFN package designed for space-constrained surface-mount applications.
Includes a dedicated shutdown pin to minimize quiescent current consumption during standby modes.

Applications

Biasing RF front-end modules requiring clean analog and digital rails
Portable battery-powered instrumentation systems
Industrial control boards with mixed-signal requirements

Procurement Notes

Verify the suffix #TRMPBF indicates tape-and-reel packaging when ordering. Confirm the 'I' grade designation matches your required operating temperature range specifications. Ensure the DC-5 variant aligns with your specific 5V output requirement rather than other voltage options in the series.

Selection Notes

Select this component when a combined boost and LDO solution is needed from a single low-voltage source. The IDC package offers thermal advantages over larger footprints. Verify that the 2.2MHz frequency suits your EMI constraints and inductor selection preferences compared to lower-frequency alternatives.

Part Context

This part belongs to the LT3048 family of dual regulators. Variants differ by output voltage configurations (e.g., -12, -15) and temperature grades (EDC vs IDC). The LT3048 series is designed to simplify power architectures by replacing separate boost and LDO components with a single integrated solution.
